When a harmful invader, such as bacteria, enters the body.. Печень играет ключевую роль в метаболизме жирных кислот, однако некоторые из них она синтезировать неспособна. Поэтому они называются незаменимыми, к таким в частности относятся ω-3- (линоленовая) и ω-6- (линолевая) полиненасыщенные жирные кислоты, они содержатся в основном в растительных жирах. Линоленовая кислота является предшественником для синтеза двух других ω-3-кислот: эйозапентаэноевой (EPA) и докозагексаэноевой (DHA)[6]. Эти вещества необходимы для работы головного мозга, и положительно влияют на когнитивные и поведенческие функции[9].

Scientists sometimes define lipids as hydrophobic or amphiphilic small molecules; the amphiphilic nature of some lipids allows them to form structures such as vesicles, multilamellar/unilamellar liposomes, or membranes in an aqueous environment. Biological lipids originate entirely or in part from two distinct types of biochemical subunits or "building-blocks": ketoacyl and isoprene groups.[4] Using this approach, lipids may be divided into eight categories: fatty acids, glycerolipids, glycerophospholipids, sphingolipids, saccharolipids, and polyketides (derived from condensation of ketoacyl subunits); and sterol lipids and prenol lipids (derived from condensation of isoprene subunits).[4] POPC:POPE:POPG lipid mix P516:P416:P616 The lipid panel test checks the lipid profile in the blood.

  5. The major dietary lipids for humans and other animals are animal and plant triglycerides, sterols, and membrane phospholipids. The process of lipid metabolism synthesizes and degrades the lipid stores and produces the structural and functional lipids characteristic of individual tissues.

In 1947, T. P. Hilditch divided lipids into "simple lipids", with greases and waxes (true waxes, sterols, alcohols). Helsingin yliopiston elintarvikeylioppilaat - Lipidi ry Почти все живые организмы запасают энергию в форме жиров. Существуют две основные причины, по которым именно эти вещества лучше всего подходят для выполнения такой функции. Во-первых, жиры содержат остатки жирных кислот, уровень окисления которых очень низкий (почти такой же как у углеводородов нефти). Поэтому полное окисление жиров до воды и углекислого газа позволяет получить более чем в два раза больше энергии, чем окисление той же массы углеводов. Во-вторых, жиры — гидрофобные соединения, поэтому организм, запасая энергию в такой форме, не должен нести дополнительной массы воды необходимой для гидратации, как в случае с полисахаридами, на 1 г которых приходится 2 г воды. Однако триглицериды — это «более медленный» источник энергии, чем углеводы. Polyketides are synthesized by polymerization of acetyl and propionyl subunits by classic enzymes as well as iterative and multimodular enzymes that share mechanistic features with the fatty acid synthases. They comprise many secondary metabolites and natural products from animal, plant, bacterial, fungal and marine sources, and have great structural diversity.[56][57] Many polyketides are cyclic molecules whose backbones are often further modified by glycosylation, methylation, hydroxylation, oxidation, or other processes. Many commonly used anti-microbial, anti-parasitic, and anti-cancer agents are polyketides or polyketide derivatives, such as erythromycins, tetracyclines, avermectins, and antitumor epothilones.[58] В современной органической химии определение термина «липиды» основано на биосинтетическом родстве данных соединений — к липидам относят жирные кислоты и их производные[4].

Суточная потребность взрослого человека в липидах — 70—145 граммов. Researchers have learned much of what they know about membranes by constructing artificial membranes in the laboratory. In artificial membranes, different lipids separate from each other based on their physical properties, forming small islands called lipid rafts The synthesis of unsaturated fatty acids involves a desaturation reaction, whereby a double bond is introduced into the fatty acyl chain. For example, in humans, the desaturation of stearic acid by stearoyl-CoA desaturase-1 produces oleic acid. The doubly unsaturated fatty acid linoleic acid as well as the triply unsaturated α-linolenic acid cannot be synthesized in mammalian tissues, and are therefore essential fatty acids and must be obtained from the diet.[93] A lipid profile (or lipid panel) is a blood test which measures the concentrations of fats and cholesterol in the blood, and can be used to assess so-called 'good cholesterol' versus..

Cholesterol is part lipid, part protein. Another type of lipid is a triglyceride. Your body needs some lipids to remain healthy, but high levels raise your risk of heart disease Sterols are steroids in which one of the hydrogen atoms is substituted with a hydroxyl group, at position 3 in the carbon chain. They have in common with steroids the same fused four-ring core structure. Steroids have different biological roles as hormones and signaling molecules. The eighteen-carbon (C18) steroids include the estrogen family whereas the C19 steroids comprise the androgens such as testosterone and androsterone. The C21 subclass includes the progestogens as well as the glucocorticoids and mineralocorticoids.[49] The secosteroids, comprising various forms of vitamin D, are characterized by cleavage of the B ring of the core structure.[50] A lipid, the scientific term for fat, is an organic molecule and a fundamental biochemical compound.

In biology and biochemistry, a lipid is a macrobiomolecule that is soluble in nonpolar solvents.[3] Non-polar solvents are typically hydrocarbons used to dissolve other naturally occurring hydrocarbon lipid molecules that do not (or do not easily) dissolve in water, including fatty acids, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, triglycerides, and phospholipids. Triglycerides, stored in adipose tissue, are a major form of energy storage both in animals and plants. They are a major source of energy because carbohydrates are fully reduced structures. In comparison to glycogen which would contribute only half of the energy per its pure mass, triglyceride carbons are all bonded to hydrogens, unlike in carbohydrates.[68] The adipocyte, or fat cell, is designed for continuous synthesis and breakdown of triglycerides in animals, with breakdown controlled mainly by the activation of hormone-sensitive enzyme lipase.[69] The complete oxidation of fatty acids provides high caloric content, about 38 kJ/g (9 kcal/g), compared with 17 kJ/g (4 kcal/g) for the breakdown of carbohydrates and proteins. Migratory birds that must fly long distances without eating use stored energy of triglycerides to fuel their flights.[70] Lipid has a high Google pagerank and bad results in terms of Yandex topical citation index.

Lipid in the largest biology dictionary online. Free learning resources for students covering all major The process wherein lipid is broken down to extract energy is called lipolysis In animals, when there is an oversupply of dietary carbohydrate, the excess carbohydrate is converted to triglycerides. This involves the synthesis of fatty acids from acetyl-CoA and the esterification of fatty acids in the production of triglycerides, a process called lipogenesis.[89] Fatty acids are made by fatty acid synthases that polymerize and then reduce acetyl-CoA units. The acyl chains in the fatty acids are extended by a cycle of reactions that add the acetyl group, reduce it to an alcohol, dehydrate it to an alkene group and then reduce it again to an alkane group. The enzymes of fatty acid biosynthesis are divided into two groups, in animals and fungi all these fatty acid synthase reactions are carried out by a single multifunctional protein,[90] while in plant plastids and bacteria separate enzymes perform each step in the pathway.[91][92] The fatty acids may be subsequently converted to triglycerides that are packaged in lipoproteins and secreted from the liver.

Lipid. Country of origin: Denmark Lipid, any of a diverse group of organic compounds including fats, oils, hormones, and certain components of membranes that are grouped together because they do not interact appreciably with water. One type of lipid, the triglycerides, is sequestered as fat in adipose cells, which serve as the energy-storage depot for organisms and also provide thermal insulation. Some lipids such as steroid hormones serve as chemical messengers between cells, tissues, and organs, and others communicate signals between biochemical systems within a single cell. The membranes of cells and organelles (structures within cells) are microscopically thin structures formed from two layers of phospholipid molecules. Membranes function to separate individual cells from their environments and to compartmentalize the cell interior into structures that carry out special functions. So important is this compartmentalizing function that membranes, and the lipids that form them, must have been essential to the origin of life itself.

I will use the lipid and fat synonymously. The simple classification of lipids based on their reactivity towards bases belies the complexity of possible lipid structures as over 1000.. Prenol lipids are synthesized from the five-carbon-unit precursors isopentenyl diphosphate and dimethylallyl diphosphate that are produced mainly via the mevalonic acid (MVA) pathway.[51] The simple isoprenoids (linear alcohols, diphosphates, etc.) are formed by the successive addition of C5 units, and are classified according to number of these terpene units. Structures containing greater than 40 carbons are known as polyterpenes. Carotenoids are important simple isoprenoids that function as antioxidants and as precursors of vitamin A.[52] Another biologically important class of molecules is exemplified by the quinones and hydroquinones, which contain an isoprenoid tail attached to a quinonoid core of non-isoprenoid origin.[53] Vitamin E and vitamin K, as well as the ubiquinones, are examples of this class. Prokaryotes synthesize polyprenols (called bactoprenols) in which the terminal isoprenoid unit attached to oxygen remains unsaturated, whereas in animal polyprenols (dolichols) the terminal isoprenoid is reduced.[54]

Beta oxidation is the metabolic process by which fatty acids are broken down in the mitochondria or in peroxisomes to generate acetyl-CoA. For the most part, fatty acids are oxidized by a mechanism that is similar to, but not identical with, a reversal of the process of fatty acid synthesis. That is, two-carbon fragments are removed sequentially from the carboxyl end of the acid after steps of dehydrogenation, hydration, and oxidation to form a beta-keto acid, which is split by thiolysis. The acetyl-CoA is then ultimately converted into ATP, CO2, and H2O using the citric acid cycle and the electron transport chain. Hence the citric acid cycle can start at acetyl-CoA when fat is being broken down for energy if there is little or no glucose available. The energy yield of the complete oxidation of the fatty acid palmitate is 106 ATP.[99] Unsaturated and odd-chain fatty acids require additional enzymatic steps for degradation. Saccharolipids describe compounds in which fatty acids are linked directly to a sugar backbone, forming structures that are compatible with membrane bilayers. In the saccharolipids, a monosaccharide substitutes for the glycerol backbone present in glycerolipids and glycerophospholipids. The most familiar saccharolipids are the acylated glucosamine precursors of the Lipid A component of the lipopolysaccharides in Gram-negative bacteria. Typical lipid A molecules are disaccharides of glucosamine, which are derivatized with as many as seven fatty-acyl chains. The minimal lipopolysaccharide required for growth in E. coli is Kdo2-Lipid A, a hexa-acylated disaccharide of glucosamine that is glycosylated with two 3-deoxy-D-manno-octulosonic acid (Kdo) residues.[55] Biological fatty acids, members of the class of compounds known as carboxylic acids, are composed of a hydrocarbon chain with one terminal carboxyl group (COOH). The fragment of a carboxylic acid not including the hydroxyl (OH) group is called an acyl group. Under physiological conditions in water, this acidic group usually has lost a hydrogen ion (H+) to form a negatively charged carboxylate group (COO−). Most biological fatty acids contain an even number of carbon atoms because the biosynthetic pathway common to all organisms involves chemically linking two-carbon units together (although relatively small amounts of odd-number fatty acids do occur in some organisms). Although the molecule as a whole is water-insoluble by virtue of its hydrophobic hydrocarbon chain, the negatively charged carboxylate is hydrophilic. This common form for biological lipids—one that contains well-separated hydrophobic and hydrophilic parts—is called amphipathic. Lipids are major sources of energy in animals and high lipid-containing seeds. Activators of enzymes eg. glucose-6-phosphatase, stearyl CoA desaturase and ω-monooxygenase..

Glycerolipids are composed of mono-, di-, and tri-substituted glycerols,[30] the best-known being the fatty acid triesters of glycerol, called triglycerides. The word "triacylglycerol" is sometimes used synonymously with "triglyceride". In these compounds, the three hydroxyl groups of glycerol are each esterified, typically by different fatty acids. Because they function as an energy store, these lipids comprise the bulk of storage fat in animal tissues. The hydrolysis of the ester bonds of triglycerides and the release of glycerol and fatty acids from adipose tissue are the initial steps in metabolizing fat.[31] Lipidi ry on yksi Viikin kampuksen suurimmista ainejärjestöistä. Lipidi ry järjestää vuosittain kaksi suurempaa ekskursiota, joista toinen suuntautuu kotimaahan ja toinen ulkomaille A few studies have suggested that total dietary fat intake is linked to an increased risk of obesity[108][109] and diabetes.[110] However, a number of very large studies, including the Women's Health Initiative Dietary Modification Trial, an eight-year study of 49,000 women, the Nurses' Health Study and the Health Professionals Follow-up Study, revealed no such links.[111][112] None of these studies suggested any connection between percentage of calories from fat and risk of cancer, heart disease, or weight gain. The Nutrition Source, a website maintained by the Department of Nutrition at the Harvard School of Public Health, summarizes the current evidence on the impact of dietary fat: "Detailed research—much of it done at Harvard—shows that the total amount of fat in the diet isn't really linked with weight or disease."[113] The "fat-soluble" vitamins (A, D, E and K) – which are isoprene-based lipids – are essential nutrients stored in the liver and fatty tissues, with a diverse range of functions. Acyl-carnitines are involved in the transport and metabolism of fatty acids in and out of mitochondria, where they undergo beta oxidation.[82] Polyprenols and their phosphorylated derivatives also play important transport roles, in this case the transport of oligosaccharides across membranes. Polyprenol phosphate sugars and polyprenol diphosphate sugars function in extra-cytoplasmic glycosylation reactions, in extracellular polysaccharide biosynthesis (for instance, peptidoglycan polymerization in bacteria), and in eukaryotic protein N-glycosylation.[83][84] Cardiolipins are a subclass of glycerophospholipids containing four acyl chains and three glycerol groups that are particularly abundant in the inner mitochondrial membrane.[85][86] They are believed to activate enzymes involved with oxidative phosphorylation.[87] Lipids also form the basis of steroid hormones.[88] 360 Lipolysis lipid soluble line Freeze Shaping Body Slim Weight Fat Loss Anti Cellulite Dissolve Fat Therapy for hyaluronic pen

What are Lipids

I lipidi, dal greco lipos ossia grasso, comprendono numerose sostanze accomunate dal fatto di essere insolubili in acqua e solubili in soluzioni apolari come cloroformio, etere e molti liquidi organici The first successful synthesis of a triglyceride molecule was by Théophile-Jules Pelouze in 1844, when he produced tributyrin by reacting butyric acid with glycerin in the presence of concentrated sulfuric acid.[12] Several years later, Marcellin Berthelot, one of Pelouze's students, synthesized tristearin and tripalmitin by reaction of the analogous fatty acids with glycerin in the presence of gaseous hydrogen chloride at high temperature.[13] Простые липиды — липиды, включающие в свою структуру углерод (С), водород (H) и кислород (O). The need for extremely high levels of insulin to maintain normoglycaemia appears to be adequate to force lipid storage in the face of adipocyte insulin resistance Молекулы простых липидов состоят из спирта, жирных кислот, сложных — из спирта, высокомолекулярных жирных кислот, возможны остатки фосфорной кислоты, углеводов, азотистых оснований и др. Строение липидов зависит в первую очередь от пути их биосинтеза.

The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes.[4][5] Lipids have applications in the cosmetic and food industries as well as in nanotechnology.[6] Производные арахидоновой кислоты — эйкозаноиды — являются примером паракринных регуляторов липидной природы. В зависимости от особенностей строения эти вещества делятся на три основные группы: простагландины, тромбоксаны и лейкориены. Они участвуют в регуляции широкого спектра физиологических функций, в частности эйкозаноиды необходимы для работы половой системы, для индукции и прохождения воспалительного процесса (в том числе обеспечение таких его аспектов как боль и повышенная температура), для свёртывания крови, регуляции кровяного давления, также они могут быть задействованы в аллергических реакциях[6].

HMG-CoA reductase inhibitors (statins) Examples of biologically important fatty acids include the eicosanoids, derived primarily from arachidonic acid and eicosapentaenoic acid, that include prostaglandins, leukotrienes, and thromboxanes. Docosahexaenoic acid is also important in biological systems, particularly with respect to sight.[27][28] Other major lipid classes in the fatty acid category are the fatty esters and fatty amides. Fatty esters include important biochemical intermediates such as wax esters, fatty acid thioester coenzyme A derivatives, fatty acid thioester ACP derivatives and fatty acid carnitines. The fatty amides include N-acyl ethanolamines, such as the cannabinoid neurotransmitter anandamide.[29] Describes how the lipid profile is used, when the lipid profile is requested, and what the results of a lipid profile might Lipid Profile.

Progress in Lipid Research. 49, 378-389 (2006). Lipid rafts: contentious only from simplistic standpoints The word "lipid", which stems etymologically from the Greek lipos (fat), was introduced in 1923 by Gabriel Bertrand.[20] Bertrands included in the concept not only the traditional fats (glycerides), but also the "lipoids", with a complex constitution.[10]

Water is the biological milieu—the substance that makes life possible—and almost all the molecular components of living cells, whether they be found in animals, plants, or microorganisms, are soluble in water. Molecules such as proteins, nucleic acids, and carbohydrates have an affinity for water and are called hydrophilic (“water-loving”). Lipids, however, are hydrophobic (“water-fearing”). Some lipids are amphipathic—part of their structure is hydrophilic and another part, usually a larger section, is hydrophobic. Amphipathic lipids exhibit a unique behaviour in water: they spontaneously form ordered molecular aggregates, with their hydrophilic ends on the outside, in contact with the water, and their hydrophobic parts on the inside, shielded from the water. This property is key to their role as the fundamental components of cellular and organelle membranes. Tässä Lipidi ry:n hallitusesittelyt vuodelle 2020. Salla Kinnunen Puheenjohtaja.

Для того чтобы увеличить срок хранения и устойчивость к высоким температурам триглицеридов с ненасыщенными жирными кислотами применяют процедуру частичной гидрогенизации. Следствием этого процесса является превращение двойных связей в одинарные, однако побочным эффектом также может быть переход двойных связей из цис- в транс-конфигурацию. Употребление так называемых «транс-жиров» влечёт повышение содержания липопротеинов низкой плотности («плохой» холестерол) и снижение содержания липопротеинов высокой плотности («хороший» холестерол) в крови, что приводит к увеличению риска возникновения сердечно-сосудистых заболеваний, в частности коронарной недостаточности.

Website Ranking Data Terpenes and isoprenoids, including the carotenoids, are made by the assembly and modification of isoprene units donated from the reactive precursors isopentenyl pyrophosphate and dimethylallyl pyrophosphate.[51] These precursors can be made in different ways. In animals and archaea, the mevalonate pathway produces these compounds from acetyl-CoA,[95] while in plants and bacteria the non-mevalonate pathway uses pyruvate and glyceraldehyde 3-phosphate as substrates.[51][96] One important reaction that uses these activated isoprene donors is steroid biosynthesis. Here, the isoprene units are joined together to make squalene and then folded up and formed into a set of rings to make lanosterol.[97] Lanosterol can then be converted into other steroids such as cholesterol and ergosterol.[97][98] Fatty acids rarely occur as free molecules in nature but are usually found as components of many complex lipid molecules such as fats (energy-storage compounds) and phospholipids (the primary lipid components of cellular membranes). This section describes the structure and physical and chemical properties of fatty acids. It also explains how living organisms obtain fatty acids, both from their diets and through metabolic breakdown of stored fats.

Жиры запасаются в форме капель в цитоплазме клетки. У позвоночных имеются специализированные клетки — адипоциты, почти полностью заполненные большой каплей жира. Также богатыми на триглицериды являются семена многих растений. Мобилизация жиров в адипоцитах и клетках прорастающих семян происходит благодаря ферментам липазам, которые расщепляют их до глицерина и жирных кислот. Важно также соотношение ω-6\ω-3-жирных кислот в рационе: рекомендуемые пропорции лежат в пределах от 1:1 до 4:1. Однако исследования показывают, что большинство жителей Северной Америки употребляют в 10-30 раз больше ω-6 жирных кислот, чем ω-3. Такое питание связано с риском возникновения сердечно-сосудистых заболеваний. Зато «средиземноморская диета» считается значительно здоровее, она богата на линоленовую и другие ω-3-кислоты, источником которых являются зелёные растения (например листья салата), рыба, чеснок, целые злаки, свежие овощи и фрукты.

LIPID CLASS (entries). Ether type lipid (547). Fat soluble vitamin (1219) Многие жиры используются организмом как источник энергии. При полном окислении 1 г жира выделяется около 9 ккал энергии, примерно вдвое больше, чем при окислении 1 г углеводов (4,1 ккал). Жировые отложения используются в качестве запасных источников питательных веществ, прежде всего животными, которые вынуждены носить свои запасы на себе. Растения чаще запасают углеводы, однако в семенах многих растений высоко содержание жиров (растительные масла добывают из семян подсолнечника, кукурузы, рапса, льна и других масличных растений). This triad of poor lipid counts often occurs in patients with premature coronary heart disease. It is also characteristic of a lipid disorder associated with insulin resistance.. Некоторые липиды играют активную роль в регулировании жизнедеятельности отдельных клеток и организма в целом. В частности, к липидам относятся стероидные гормоны, секретируемые половыми железами и корой надпочечников. Эти вещества переносятся кровью по всему организму и влияют на его функционирование.

Особенно толстый подкожный жировой слой характерен для водных млекопитающих (китов, моржей и др.). Но в то же время у животных, обитающих в условиях жаркого климата (верблюды, тушканчики) жировые запасы откладываются на изолированных участках тела (в горбах у верблюда, в хвосте у жирнохвостых тушканчиков) в качестве резервных запасов воды, так как вода — один из продуктов окисления жиров. Lipidi ретвитнул(а). Sal the Agorist‏ @SallyMayweather 3 ч3 часа назад A lipid is any of various organic compounds that are insoluble in water. They include fats, waxes, oils, hormones, and certain components of membranes and function as energy-storage molecules and chemical messengers. Together with proteins and carbohydrates, lipids are one of the principal structural components of living cells.

In 1827, William Prout recognized fat ("oily" alimentary matters), along with protein ("albuminous") and carbohydrate ("saccharine"), as an important nutrient for humans and animals.[14][15] Толстый слой жира защищает внутренние органы многих животных от повреждений при ударах (например, сивучи при массе до тонны могут прыгать в воду со скал высотой 20-25 м[источник не указан 2781 день]). In addition to straight-chain hydrocarbons, fatty acids may also contain pairs of carbons linked by one or more double bonds, methyl branches, or a three-carbon cyclopropane ring near the centre of the carbon chain. Lipid definition, any of a group of organic compounds that are greasy to the touch, insoluble in water, and soluble in alcohol and ether: lipids comprise the fats and other..

Sterols, such as cholesterol and its derivatives, are an important component of membrane lipids,[45] along with the glycerophospholipids and sphingomyelins. Other examples of sterols are the bile acids and their conjugates,[46] which in mammals are oxidized derivatives of cholesterol and are synthesized in the liver. The plant equivalents are the phytosterols, such as β-sitosterol, stigmasterol, and brassicasterol; the latter compound is also used as a biomarker for algal growth.[47] The predominant sterol in fungal cell membranes is ergosterol.[48] Lipid bilayers. The Martini course-grained (CG) model was originally developed for The aim of the tutorial is to create and study properties of CG Martini models of lipid bilayer.. In 1815, Henri Braconnot classified lipids (graisses) in two categories, suifs (solid greases or tallow) and huiles (fluid oils).[8] In 1823, Michel Eugène Chevreul developed a more detailed classification, including oils, greases, tallow, waxes, resins, balsams and volatile oils (or essential oils).[9][10][11] Lipid Classes. simple: FAs esterified with glycerol compound: same as simple, but with other compounds also attached phospholipids: fats containing phosphoric acid and..
