Tetradecanoic acid is an oily white crystalline solid. (NTP, 1992) Tetradecanoic acid is a straight-chain, fourteen-carbon, long-chain saturated fatty acid mostly found in milk fat. It has a role as a human metabolite, an EC 3.1.1.1 (carboxylesterase) inhibitor, a Daphnia magna metabolite and an algal metabolite. It is a long-chain fatty acid and a straight-chain saturated fatty acid. It is a conjugate acid of a tetradecanoate. Myristic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Myristic acid is a natural product found in Gladiolus italicus, Staphisagria macrosperma, and other organisms with data available. Myristic Acid is a saturated long-chain fatty acid with a 14-carbon backbone. Myristic acid is found naturally in palm oil, coconut oil and butter fat. Myristic acid is a saturated 14-carbon fatty acid occurring in most animal and vegetable fats, particularly butterfat and coconut, palm, and nutmeg oils. It is used to synthesize flavor and as an ingredient in soaps and cosmetics. (From Dorland, 28th ed). Myristic acid is also commonly added to a penultimate nitrogen terminus glycine in receptor-associated kinases to confer the membrane localisation of the enzyme. this is achieved by the myristic acid having a high enough hydrophobicity to become incorporated into the fatty acyl core of the phospholipid bilayer of the plasma membrane of the eukaryotic cell.(wikipedia). myristic acid is a metabolite found in or produced by Saccharomyces cerevisiae. A saturated 14-carbon fatty acid occurring in most animal and vegetable fats, particularly butterfat and coconut, palm, and nutmeg oils. It is used to synthesize flavor and as an ingredient in soaps and cosmetics. (From Dorland, 28th ed) See also: Cod Liver Oil (part of); Saw Palmetto (part of). Myristic acid, also known as tetradecanoic acid or C14:0, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Myristic acid (its ester is called myristate) is a saturated fatty acid that has 14 carbons; as such, it is a very hydrophobic molecule that is practically insoluble in water. It exists as an oily white crystalline solid. Myristic acid is found in all living organisms ranging from bacteria to plants to animals, and is found in most animal and vegetable fats, particularly butterfat, as well as coconut, palm, and nutmeg oils. Industrially, myristic acid is used to synthesize a variety of flavour compounds and as an ingredient in soaps and cosmetics (Dorland, 28th ed). Within eukaryotic cells, myristic acid is also commonly conjugated to a penultimate N-terminal glycine residue in receptor-associated kinases to confer membrane localization of these enzymes (a post-translational modification called myristoylation via the enzyme N-myristoyltransferase). Myristic acid has a high enough hydrophobicity to allow the myristoylated protein to become incorporated into the fatty acyl core of the phospholipid bilayer of the plasma membrane of eukaryotic cells. Also, this fatty acid is known because it accumulates as fat in the body; however, its consumption also impacts positively on cardiovascular health (see, for example, PMID: 15936650). Myristic acid is named after the scientific name for nutmeg, Myristica fragrans, from which it was first isolated in 1841 by Lyon Playfair. Myristic acid, also known as 14 or N-tetradecanoic acid, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, myristic acid is considered to be a fatty acid lipid molecule. Myristic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Myristic acid can be found in a number of food items such as strawberry, barley, nutmeg, and soy bean, which makes myristic acid a potential biomarker for the consumption of these food products. Myristic acid can be found primarily in most biofluids, including cerebrospinal fluid (CSF), blood, saliva, and feces, as well as throughout most human tissues. Myristic acid exists in all living species, ranging from bacteria to humans. In humans, myristic acid is involved in the fatty acid biosynthesis. Moreover, myristic acid is found to be associated with schizophrenia. Myristic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Myristic acid (IUPAC systematic name: 1-tetradecanoic acid) is a common saturated fatty acid with the molecular formula CH3(CH2)12COOH. Its salts and esters are commonly referred to as myristates.

Palmitic acid, also known as palmitate or hexadecanoic acid, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, palmitic acid is considered to be a fatty acid lipid molecule. Palmitic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Palmitic acid can be found in a number of food items such as sacred lotus, spinach, shallot, and corn salad, which makes palmitic acid a potential biomarker for the consumption of these food products. Palmitic acid can be found primarily in most biofluids, including feces, sweat, cerebrospinal fluid (CSF), and urine, as well as throughout most human tissues. Palmitic acid exists in all living species, ranging from bacteria to humans. In humans, palmitic acid is involved in several metabolic pathways, some of which include alendronate action pathway, rosuvastatin action pathway, simvastatin action pathway, and cerivastatin action pathway. Palmitic acid is also involved in several metabolic disorders, some of which include hypercholesterolemia, familial lipoprotein lipase deficiency, ethylmalonic encephalopathy, and carnitine palmitoyl transferase deficiency (I). Moreover, palmitic acid is found to be associated with schizophrenia. Palmitic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Palmitic acid, or hexadecanoic acid in IUPAC nomenclature, is the most common saturated fatty acid found in animals, plants and microorganisms. Its chemical formula is CH3(CH2)14COOH, and its C:D is 16:0. As its name indicates, it is a major component of the oil from the fruit of oil palms (palm oil). Palmitic acid can also be found in meats, cheeses, butter, and dairy products. Palmitate is the salts and esters of palmitic acid. The palmitate anion is the observed form of palmitic acid at physiologic pH (7.4) . Palmitic acid is the first fatty acid produced during lipogenesis (fatty acid synthesis) and from which longer fatty acids can be produced. Palmitate negatively feeds back on acetyl-CoA carboxylase (ACC) which is responsible for converting acetyl-ACP to malonyl-ACP on the growing acyl chain, thus preventing further palmitate generation (DrugBank). Palmitic acid, or hexadecanoic acid, is one of the most common saturated fatty acids found in animals, plants, and microorganisms. As its name indicates, it is a major component of the oil from the fruit of oil palms (palm oil). Excess carbohydrates in the body are converted to palmitic acid. Palmitic acid is the first fatty acid produced during fatty acid synthesis and is the precursor to longer fatty acids. As a consequence, palmitic acid is a major body component of animals. In humans, one analysis found it to make up 21–30\\\% (molar) of human depot fat (PMID: 13756126), and it is a major, but highly variable, lipid component of human breast milk (PMID: 352132). Palmitic acid is used to produce soaps, cosmetics, and industrial mould release agents. These applications use sodium palmitate, which is commonly obtained by saponification of palm oil. To this end, palm oil, rendered from palm tree (species Elaeis guineensis), is treated with sodium hydroxide (in the form of caustic soda or lye), which causes hydrolysis of the ester groups, yielding glycerol and sodium palmitate. Aluminium salts of palmitic acid and naphthenic acid were combined during World War II to produce napalm. The word "napalm" is derived from the words naphthenic acid and palmitic acid (Wikipedia). Palmitic acid is also used in the determination of water hardness and is a surfactant of Levovist, an intravenous ultrasonic contrast agent. Hexadecanoic acid is a straight-chain, sixteen-carbon, saturated long-chain fatty acid. It has a role as an EC 1.1.1.189 (prostaglandin-E2 9-reductase) inhibitor, a plant metabolite, a Daphnia magna metabolite and an algal metabolite.

Eicosapentaenoic acid

cis, cis, cis, cis, cis-Eicosa-5,8,11,14,17-pentaenoic acid

C20H30O2 (302.2246)


Icosapent, also known as icosapentaenoate or (5z,8z,11z,14z,17z)-eicosapentaenoic acid, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, icosapent is considered to be a fatty acid lipid molecule. Icosapent is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Icosapent can be found in a number of food items such as barley, sacred lotus, white lupine, and rape, which makes icosapent a potential biomarker for the consumption of these food products. Icosapent can be found primarily in blood, feces, sweat, and urine, as well as throughout most human tissues. In humans, icosapent is involved in the alpha linolenic acid and linoleic acid metabolism. Moreover, icosapent is found to be associated with essential hypertension and hypertension. Ethyl eicosapentaenoic acid (E-EPA, icosapent ethyl) is a derivative of the omega-3 fatty acid eicosapentaenoic acid (EPA) that is used in combination with changes in diet to lower triglyceride levels in adults with severe (≥ 500 mg/dL) hypertriglyceridemia. This was the second class of fish oil-based drug to be approved for use as a drug and was approved by the FDA in 2012. These fish oil drugs are similar to fish oil dietary supplements but the ingredients are better controlled and have been tested in clinical trials . The anti-inflammatory, antithrombotic and immunomodulatory actions of EPA is probably due to its role in eicosanoid physiology and biochemistry. Most eicosanoids are produced by the metabolism of omega-3 fatty acids, specifically, arachidonic acid. These eicosanoids, leukotriene B4 (LTB4) and thromboxane A2 (TXA2) stimulate leukocyte chemotaxis, platelet aggregation and vasoconstriction. They are thrombogenic and artherogenic. On the other hand, EPA is metabolized to leukotriene B5 (LTB5) and thromboxane A3 (TXA3), which are eicosanoids that promote vasodilation, inhibit platelet aggregation and leukocyte chemotaxis and are anti-artherogenic and anti-thrombotic. The triglyceride-lowering effect of EPA results from inhibition of lipogenesis and stimulation of fatty acid oxidation. Fatty acid oxidation of EPA occurs mainly in the mitochondria. EPA is a substrate for Prostaglandin-endoperoxide synthase 1 and 2. It also appears to affect the function and bind to the Carbohydrate responsive element binding protein (ChREBP) and to a fatty acid receptor (G-coupled receptor) known as GP40 (DrugBank). Eicosapentaenoic acid (EPA or also icosapentaenoic acid) is an important polyunsaturated fatty acid found in fish oils. It serves as the precursor for the prostaglandin-3 and thromboxane-3 families. A diet rich in eicosapentaenoic acid lowers serum lipid concentration, reduces incidence of cardiovascular disorders, prevents platelet aggregation, and inhibits arachidonic acid conversion into the thromboxane-2 and prostaglandin-2 families. Eicosapentaenoic acid is an omega-3 fatty acid. In physiological literature, it is given the name 20:5(n-3). Its systematic chemical name is all-cis-5,8,11,14,17-icosapentaenoic acid. It also has the trivial name timnodonic acid. Chemically, EPA is a carboxylic acid with a 20-carbon chain and five cis double bonds; the first double bond is located at the third carbon from the omega end. Because of the presence of double bonds, EPS is a polyunsaturated fatty acid. Metabolically it acts as a precursor for prostaglandin-3 (which inhibits platelet aggregation), thromboxane-3, and leukotriene-5 groups. It is found in fish oils of cod liver, herring, mackerel, salmon, menhaden, and sardine. It is also found in human breast milk (Wikipedia).

As its ester, stearic acid is one of the most common saturated fatty acids found in nature following palmitic acid. The triglyceride derived from three molecules of stearic acid is called stearin . Stearic acid, also known as octadecanoic acid or C18:0, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Stearic acid (its ester is called stearate) is a saturated fatty acid that has 18 carbons and is therefore a very hydrophobic molecule that is practically insoluble in water. It exists as a waxy solid. In terms of its biosynthesis, stearic acid is produced from carbohydrates via the fatty acid synthesis machinery wherein acetyl-CoA contributes two-carbon building blocks, up to the 16-carbon palmitate, via the enzyme complex fatty acid synthase (FA synthase), at which point a fatty acid elongase is needed to further lengthen it. After synthesis, there are a variety of reactions it may undergo, including desaturation to oleate via stearoyl-CoA desaturase (PMID: 16477801). Stearic acid is found in all living organisms ranging from bacteria to plants to animals. It is one of the useful types of saturated fatty acids that comes from many animal and vegetable fats and oils. For example, it is a component of cocoa butter and shea butter. It is used as a food additive, in cleaning and personal care products, and in lubricants. Its name comes from the Greek word stear, which means ‚Äòtallow‚Äô or ‚Äòhard fat‚Äô.

20-Hydroxyeicosatetraenoic acid

(5Z,8Z,11Z,14Z)-20-Hydroxyicosa-5,8,11,14-tetraenoic acid

C20H32O3 (320.2351)


20-Hydroxyeicosatetraenoic acid (20-HETE) is a metabolite of arachidonic acid. Cytochrome P450 enzymes of the 4A and 4F families catalyze the omega-hydroxylation of arachidonic acid and produce 20-HETE. 20-HETE is a potent constrictor of renal, cerebral, and mesenteric arteries. The vasoconstrictor response to 20-HETE is associated with activation of protein kinase, Rho kinase, and the mitogen-activated protein (MAP) kinase pathway C. 20-HETE also increases intracellular Ca2+ by causing the depolarization of vascular smooth muscle membrane secondary to blocking the large-conductance Ca2+-activated K+-channels and by a direct effect on L-type Ca channels. Elevations in the production of 20-HETE mediate the myogenic response of skeletal, renal, and cerebral arteries to elevations in transmural pressure. There is an important interaction between nitric oxide (NO) and the formation of 20-HETE production. NO inhibits the formation of 20-HETE formation in renal and cerebral arteries. A fall in levels of 20-HETE contributes to the cyclic GMP-independent dilator effect of NO to activate the large-conductance Ca2+-activated K+-channels and to dilate the cerebral arteries (PMID: 16258232). Metabolite produced during NADPH dependent enzymatic oxidation of arachidonic acid. Potent vasoconstrictor [CCD]

16-Hydroxyhexadecanoic acid

16-hydroxyhexadecanoic acid

C16H32O3 (272.2351)


16-Hydroxyhexadecanoic acid, also known as 16-hydroxypalmitic acid, is a hydroxylated fatty acid where the terminal (omega) carbon has been hydroxylated. In animal tissues, a family of enzymes termed cytochromes P450s are involved in fatty acid oxidation, hydroxylating with high specificity at the energetically unfavourable terminal (omega) or omega-1 carbons. Hydroxy fatty acids primarily come from the consumption of plant products (vegetables or fruits) or cow’s milk. Omega hydroxy fatty acids are found in the structure of suberin, a lipid polyester present in plant cell walls, and of cutin, a lipid polyester which is a component of the plant cuticle. These apoplastic structures are important plant-environment interfaces that act as barriers limiting water and nutrient loss and protecting plants from radiation and pathogens. 16-Hydroxyhexadecanoic acid and 18-hydroxystearic acid are particularly abundant in cutin in the plant cuticle. 16-Hydroxyhexadecanoic acid has been proposed as a biomarker of beer consumption. 16-hydroxy-hexadecanoic acid, also known as 16-hydroxypalmitic acid or 16-oh 16:0, is a member of the class of compounds known as long-chain fatty acids.

C18H34O2 (282.2559)


Oleic acid (or 9Z)-Octadecenoic acid) is an unsaturated C-18 or an omega-9 fatty acid that is the most widely distributed and abundant fatty acid in nature. It occurs naturally in various animal and vegetable fats and oils. It is an odorless, colorless oil, although commercial samples may be yellowish. The name derives from the Latin word oleum, which means oil. Oleic acid is the most abundant fatty acid in human adipose tissue, and the second most abundant in human tissues overall, following palmitic acid. Oleic acid is a component of the normal human diet, being a part of animal fats and vegetable oils. Triglycerides of oleic acid represent the majority of olive oil (about 70\\\\%).

Arachidonic acid

(5Z,8Z,11Z,14Z)-icosa-5,8,11,14-tetraenoic acid

C20H32O2 (304.2402)


Arachidonic acid is a polyunsaturated, essential fatty acid that has a 20-carbon chain as a backbone and four cis-double bonds at the C5, C8, C11, and C14 positions. It is found in animal and human fat as well as in the liver, brain, and glandular organs, and is a constituent of animal phosphatides. It is synthesized from dietary linoleic acid. Arachidonic acid mediates inflammation and the functioning of several organs and systems either directly or upon its conversion into eicosanoids. Arachidonic acid in cell membrane phospholipids is the substrate for the synthesis of a range of biologically active compounds (eicosanoids) including prostaglandins, thromboxanes, and leukotrienes. These compounds can act as mediators in their own right and can also act as regulators of other processes, such as platelet aggregation, blood clotting, smooth muscle contraction, leukocyte chemotaxis, inflammatory cytokine production, and immune function. Arachidonic acid can be metabolized by cytochrome p450 (CYP450) enzymes into 5,6-, 8,9-, 11,12-, and 14,15-epoxyeicosatrienoic acids (EETs), their corresponding dihydroxyeicosatrienoic acids (DHETs), and 20-hydroxyeicosatetraenoic acid (20-HETE). The production of kidney CYP450 arachidonic acid metabolites is altered in diabetes, pregnancy, hepatorenal syndrome, and in various models of hypertension, and it is likely that changes in this system contribute to the abnormalities in renal function that are associated with many of these conditions. Phospholipase A2 (PLA2) catalyzes the hydrolysis of the sn-2 position of membrane glycerophospholipids to liberate arachidonic acid (PMID: 12736897, 12736897, 12700820, 12570747, 12432908). The beneficial effects of omega-3 fatty acids are believed to be due in part to selective alteration of arachidonate metabolism that involves cyclooxygenase (COX) enzymes (PMID: 23371504). 9-Oxononanoic acid (9-ONA), one of the major products of peroxidized fatty acids, was found to stimulate the activity of phospholipase A2 (PLA2), the key enzyme to initiate the arachidonate cascade and eicosanoid production (PMID: 23704812). Arachidonate lipoxygenase (ALOX) enzymes metabolize arachidonic acid to generate potent inflammatory mediators and play an important role in inflammation-associated diseases (PMID: 23404351).

20-Carboxy-leukotriene B4

(5S,6Z,8E,10E,12R,14Z)-5,12-Dihydroxyicosa-6,8,10,14-tetraenedioic acid

C20H30O6 (366.2042)


20-Carboxyleukotriene B4 is an omega-oxidized metabolite of leukotriene B4 (LTB4). Neutrophil microsomes are known to oxidize 20-hydroxy-LTB4 (20-OH-LTB4) to its 20-oxo and 20-carboxy derivatives in the presence of NADPH. This activity has been ascribed to LTB4 omega-hydroxylase (cytochrome P-450LTB omega). Leukotriene B4 release from polymorphonuclear granulocytes of severely burned patients was reduced as compared to healthy donor cells. This decrease is due to an enhanced conversion of LTB4 into the 20-hydroxy- and 20-carboxy-metabolites and further to a decreased LTB4-synthesis. LTB4 is the major metabolite in neutrophil polymorphonuclear leukocytes. Leukotrienes are metabolites of arachidonic acid derived from the action of 5-LO (5-lipoxygenase). The immediate product of 5-LO is LTA4 (leukotriene A4), which is enzymatically converted into either LTB4 (leukotriene B4) by LTA4 hydrolase or LTC4 (leukotriene C4) by LTC4 synthase. The regulation of leukotriene production occurs at various levels, including expression of 5-LO, translocation of 5-LO to the perinuclear region and phosphorylation to either enhance or inhibit the activity of 5-LO. Biologically active LTB4 is metabolized by w-oxidation carried out by specific cytochrome P450s (CYP4F) followed by beta-oxidation from the w-carboxy position and after CoA ester formation. Other specific pathways of leukotriene metabolism include the 12-hydroxydehydrogenase/ 15-oxo-prostaglandin-13-reductase that form a series of conjugated diene metabolites that have been observed to be excreted into human urine. Metabolism of LTC4 occurs by sequential peptide cleavage reactions involving a gamma-glutamyl transpeptidase that forms LTD4 (leukotriene D4) and a membrane-bound dipeptidase that converts LTD4 into LTE4 (leukotriene E4) before w-oxidation. These metabolic transformations of the primary leukotrienes are critical for termination of their biological activity, and defects in expression of participating enzymes may be involved in specific genetic disease. (PMID 17623009, 7633595, 2155225, 3039534)Leukotrienes are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways.

Human platelets metabolize 8,11,14,17-eicosatetraenoic acid primarily into 12-hydroxy-8,10,14,17-eicosatetraenoic acid. The eicosanoids are a diverse family of molecules that have powerful effects on cell function. They are best known as intercellular messengers, having autocrine and paracrine effects following their secretion from the cells that synthesize them. The diversity of possible products that can be synthesized from eicosatrienoic acid is due, in part to the variety of enzymes that can act on it. Studies have placed many, but not all, of these enzymes at or inside the nucleus. In some cases, the nuclear import or export of eicosatrienoic acid-processing enzymes is highly regulated. Furthermore, nuclear receptors that are activated by specific eicosanoids are known to exist. Taken together, these findings indicate that the enzymatic conversion of eicosatrienoic acid to specific signaling molecules can occur in the nucleus, that it is regulated, and that the synthesized products may act within the nucleus.

C20H30O6 (366.2042)


12-oxo-10,11-dihydro-20-COOH-LTB4 is formed when leukotriene B4 (LTB4) is metabolized by beta-oxidation. LTB4 is the major metabolite in neutrophil polymorphonuclear leukocytes. Leukotrienes are metabolites of arachidonic acid derived from the action of 5-LO (5-lipoxygenase). The immediate product of 5-LO is LTA4 (leukotriene A4), which is enzymatically converted into either LTB4 (leukotriene B4) by LTA4 hydrolase or LTC4 (leukotriene C4) by LTC4 synthase. The regulation of leukotriene production occurs at various levels, including expression of 5-LO, translocation of 5-LO to the perinuclear region and phosphorylation to either enhance or inhibit the activity of 5-LO. Biologically active LTB4 is metabolized by w-oxidation carried out by specific cytochrome P450s (CYP4F) followed by beta-oxidation from the w-carboxy position and after CoA ester formation. (PMID: 8632343, 9667737). Leukotrienes are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways. 12-oxo-10,11-dihydro-20-COOH-LTB4 is formed when leukotriene B4 (LTB4) is metabolized by beta-oxidation.

cis-Vaccenic acid

(11Z)-octadec-11-enoic acid

C18H34O2 (282.2559)


cis-11-Octadecenoic acid, also known as (Z)-octadec-11-enoic acid or asclepic acid, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. cis-11-Octadecenoic acid is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Occurs in small proportions in ruminant fats (e.g., butter) via biohydrogenation of dietary polyene acids. Vaccenic acid is found in many foods, some of which are almond, romaine lettuce, butter, and pak choy. trans-Vaccenic acid is a precursor for the synthesis of saturated fatty acid in the rumen and of conjugated linoleic acid (CLA) at the tissue level. trans-Vaccenic acid is a precursor for the synthesis of saturated fatty acid in the rumen and of conjugated linoleic acid (CLA) at the tissue level.

   

N-Linoleoyl Glycine

15-Methylhexadecanoic acid

C20H35NO3 (337.2617)


N-linoleoyl glycine, also known as 15-methylpalmitate or C17ISO belongs to the class of compounds known as N-acylamides. These are molecules characterized by a fatty acyl group linked to a primary amine by an amide bond. More specifically, it is a Linoleic acid amide of Glycine. It is believed that there are more than 800 types of N-acylamides in the human body. N-acylamides fall into several categories: amino acid conjugates (e.g., those acyl amides conjugated with amino acids), neurotransmitter conjugates (e.g., those acylamides conjugated with neurotransmitters), ethanolamine conjugates (e.g., those acylamides conjugated to ethanolamine), and taurine conjugates (e.g., those acyamides conjugated to taurine). N-Linoleoyl Glycine is an amino acid conjugate. N-acylamides can be classified into 9 different categories depending on the size of their acyl-group: 1) short-chain N-acylamides; 2) medium-chain N-acylamides; 3) long-chain N-acylamides; and 4) very long-chain N-acylamides; 5) hydroxy N-acylamides; 6) branched chain N-acylamides; 7) unsaturated N-acylamides; 8) dicarboxylic N-acylamides and 9) miscellaneous N-acylamides. N-Linoleoyl Glycine is therefore classified as a long chain N-acylamide. N-acyl amides have a variety of signaling functions in physiology, including in cardiovascular activity, metabolic homeostasis, memory, cognition, pain, motor control and others (PMID: 15655504). N-acyl amides have also been shown to play a role in cell migration, inflammation and certain pathological conditions such as diabetes, cancer, neurodegenerative disease, and obesity (PMID: 23144998; PMID: 25136293; PMID: 28854168).N-acyl amides can be synthesized both endogenously and by gut microbiota (PMID: 28854168). N-acylamides can be biosynthesized via different routes, depending on the parent amine group. N-acyl ethanolamines (NAEs) are formed via the hydrolysis of an unusual phospholipid precursor, N-acyl-phosphatidylethanolamine (NAPE), by a specific phospholipase D. N-acyl amino acids are synthesized via a circulating peptidase M20 domain containing 1 (PM20D1), which can catalyze the bidirectional the condensation and hydrolysis of a variety of N-acyl amino acids. The degradation of N-acylamides is largely mediated by an enzyme called fatty acid amide hydrolase (FAAH), which catalyzes the hydrolysis of N-acylamides into fatty acids and the biogenic amines. Many N-acylamides are involved in lipid signaling system through interactions with transient receptor potential channels (TRP). TRP channel proteins interact with N-acyl amides such as N-arachidonoyl ethanolamide (Anandamide), N-arachidonoyl dopamine and others in an opportunistic fashion (PMID: 23178153). This signaling system has been shown to play a role in the physiological processes involved in inflammation (PMID: 25136293). Other N-acyl amides, including N-oleoyl-glutamine, have also been characterized as TRP channel antagonists (PMID: 29967167). N-acylamides have also been shown to have G-protein-coupled receptors (GPCRs) binding activity (PMID: 28854168). The study of N-acylamides is an active area of research and it is likely that many novel N-acylamides will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered for these molecules.

5,8,11-Eicosatrienoic acid (Mead acid) is a carboxylic acid with a 20-carbon chain and three methylene-interrupted cis double bonds. The first double bond is located at the ninth carbon from the omega end. In physiological literature, it is given the name 20:3(n-9). In the presence of lipoxygenase, Mead acid can form various hydroxy products (HETE). It is the only polyunsaturated fatty acid that the body can make de novo. Its elevated presence in the blood is an indication of essential fatty acid (EFA)deficiency. During dietary EFA insufficiency, especially arachidonic acid deficiency, the body will make Mead acid by the elongation and desaturation of oleic acid. [HMDB]
