Generally considerd to be predominant fatty acid in nature (few fats known to contain less than 10%; Separation from olive oil by double fraction via urea adduct(Ref. 4003). Major constituent in plant oils e.g. olive oil (about 80%), almond oil (about 80%), mainly as glyceride.
Purest product (98%) obtained when the oil was saponified with 3% KOH solution; Synthesis(Ref. 4008)
In animals oleic acid is synthsized from stearoyl CoA by oxidative desaturation using O2, NADPH, cytochrome b5. Oleic acid is further metabolized to 20:9n-9 via reactions of desaturation and elongation. Essential fatty acid deficincy causes the accumulation of 20:9n-9.

C18H32O2 280.445 Download ChemDraw structure fileDownload mol format file
There are two groups of essential fatty acids for mammals, the n-6 (or w6) and the n-3 (or w3). Linoleic acid (LA) is one of the n-6 essential fatty. Animals deficient in LA show the growth retardation, skin lesions, reproductive failure, fatty liver and polydipsia (Ref. 2009/2010). Dietary supplementation of either linoleate, g-linoleate or arachidonate prevents such symptoms completely. Its physiological functions appear to be mediated mainly through the hormone-like eicosanoids (prostaglandins, leukotriens and thromboxanes et al.) derived from arachidonic acid which is biosynthesized from LA. LA is also shown to be involved in control of the water impermeability of the skin and regulation of cholesterol synthesis and transport.

Gas liquid chromatogram

Constituent of the essential fatty acids (vitamin F) and of various microorganisms; oils of cottonseed, soybean, peanut, corn, sunflower and poppy seed.

Linoleic acid (18:2n-6) is synthesized from oleic acid (18:1n-9) by desaturation of D12-desaturase, and a-linolenic acid (18:3n-3) is formed from linoleic acid by desaturation reaction of D15-desaturase. Since both D12- and 15-desaturases are present in plant cells but not in animal cells, linoleic and a-linolenic acid are not biosynthesized in animal cells in vivo. When ingested by animals, linoleic acid is desaturated, elongated to form g-linolenic acid (18:3n-6), dihomo-g-linolenic acid (20:3n-6), arachidonic acid (20:4n-6) and adrenic acid (22:4n-6). Docosapentaenoic acid (22:5n-6) is synthesized from adrenic acid in significant amounts only under conditions of prolonged n-3 fatty acid deficiency.
No interconversion between the n-6 and n-3 series in mammals. Nutritionally, it is important to note that different foods contain different proportions of n-6/n-3 and therefore the n-6/n-3 ratio in tissue lipids change significantly depending on the choice of foods.(Ref. 2003) Although plants synthesize and store linoleic acid and a-linolenic acid as well as saturated and monounsaturated fatty acids in grains, the proportions of these fatty acids in different vegetable oils differ greatly. Safflower and sunflower oil contain high levels of linoleate, while perilla and linseed oil are rich in a-linolenic acid.

There are two groups of essential fatty acids, the n-6 (or w6) and the n-3 (or w3). g-linolenic acid is n-6 fatty acids. Essential fatty acid deficiency causes skin lesion and growth retardation. Dietary supplementation of either linoleate, g-linoleate or arachidonate prevents such symptoms completely. The n-6 essential fatty acids have at least four roles (Ref. 2014): 1) Modulation of membrane structure. 2) Formation of short-lived giologically active molecules. Oxygenated derivatives of g-linolenic acid is a Arachidonic acid may have a role in the regulation of cell devision in cancer and other cells. There are other bioactive substance, PGE1 and 15-OH-dihomogamma-linolenic acid which are both formed from g-linolenic acid after its rapid elongation to dihomogamma-linolenic acid. 3) Control of the water impermeability of the skin. 4) Regulation of cholesterol synthesis and transport.

Isolated from seeds of Oenothera biennis and O. lamarckiana (evening primroses); drying oils. A minor component of many animal lipids.

Linoleic acid (18:2n-6) is synthesized from oleic acid (18:1n-9) by desaturation of D12-desaturase, and a-linolenic acid (18:3n-3) is formed from linoleic acid by desaturation reaction of D15-desaturase. Since both D12- and 15-desaturases are present in plant cells but not in animal cells, linoleic and a-linolenic acid are not biosynthesized in animal cells in vivo. When ingested by animals, linoleic acid is desaturated, elongated to form g-linolenic acid (18:3n-6), dihomo-g-linolenic acid (20:3n-6), arachidonic acid (20:4n-6) and adrenic acid (22:4n-6). Docosapentaenoic acid (22:5n-6) is synthesized from adrenic acid in significant amounts only under conditions of prolonged n-3 fatty acid deficiency.
No interconversion between the n-6 and n-3 series in mammals. Nutritionally, it is important to note that different foods contain different proportions of n-6/n-3 and therefore the n-6/n-3 ratio in tissue lipids change significantly depending on the choice of foods.(Ref. 2003)

Dietary a-linolenic acid can be further elongated and desaturated to form the long-chain n-3 fatty acids, such as eicosapentaenoic acid (EPA) and docosapentaenoic acid (DHA), which are uniquely rich in neural membranes of retina and brain in mammals. It has been reported that n-3 fatty acid deficiency produces reduced learning ability(Ref. 2005), impaired vision, abnormal electroretinogram(Ref. 2006/2007) and polydipsia(Ref. 2008). Dietary fat manipulation of perilla oil rich in a-linolenic acid reduces colonic damage in experimental Crohn's disease (Ref. 2015/2016).

Linoleic acid (18:2n-6) is synthesized from oleic acid (18:1n-9) by desaturation of D12-desaturase, and a-linolenic acid (18:3n-3) is formed from linoleic acid by desaturation reaction of D15-desaturase. Since both D12- and 15-desaturases are present in plant cells, a-linolenic acid is synthesized in plants, and relatively enriched in leaves (photosynthetic tissues). On the other hand, these desaturases are not present in animal cells, neither linoleic nor a-linolenic acid is biosynthesized in animal cells in vivo. When ingested by animals, a-linolenic acid is desaturated, elongated and chain-shortened to form eicosapantaenoic acid (20:5n-3, EPA) and docosahexaenoic acid (22:6n-3, DHA)(Ref. 2001/2002). No interconversion between the n-6 and n-3 series in mammals.
Nutritionally, it is important to note that different foods contain different proportions of n-6/n-3 and therefore the n-6/n-3 ratio in tissue lipids change significantly depending on the choice of foods. Although plants synthesize and store linoleic acid and a-linolenic acid as well as saturated and monounsaturated fatty acids in grains, the proportions of these fatty acids in different vegetable oils differ greatly. Safflower and sunflower oil contain high levels of linoleate, while perilla and linseed oil are rich in a-linolenic acid.

The synthesis of 5,8,11,14,17-20:5 (=EPA) occurs via the following reaction sequence in the endoplasmic reticulum (Ref. 2013): 9,12,15-18:3 --> 6,9,12,15-18:4 --> 8,11,14,17-20:4 --> 5,8,11,14,17-20:5 --> 7,10,13,16,19-22:5.

According to these pathways the 24-carbon acids that are made in the endoplasmic reticulum move to a site for partial beta-oxidation, which is most likely peroxisomes.

DHA is one of the n-3 (w3) fatty acids. It is uniquely rich in neural membranes of retina and brain in mammals. n-3 fatty acid deficiency causes the reduction of DHA level in these tissues and produces reduced learning ability (Ref. 2005), impaired vision, abnormal electroretinogram (Ref. 2006/2007) and polydipsia (Ref. 2008). It is believed to be important for the full development of the nervous system in the fetus and newborn.(Ref. 2003) Considered, along with EPA, to be the major reason for the beneficial effects of fish oils on the cardiovascular system. Anti-inflammatory (Ref. 2021/2022/2024), anti-thrombotic (Ref. 2023), anti-arteriosclerosis (Ref. 2022/2025) and anti-cancer activities (Ref. 2026/2027) have been reported. Production of bioactive metabolites, eicosanoids, is suppressed by DHA. DHA can be also involved in the modulation of membrane structures (Ref. 2017/2018).

Metabolic product of a-linolenic acid (9,12,25-18:3). The synthesis of 4,7,10,13,16,19-22:6 (=DHA) occurs via the following reaction sequence (Ref. 2013): 9,12,15-18:3 --> 6,9,12,15-18:4 --> 8,11,14,17-20:4 --> 5,8,11,14,17-20:5 --> 7,10,13,16,19-22:5 --> 9,12,15,18,21-24:5 --> 6,9,12,15,18,21-24:6 --> 4,7,10,13,16,19-22:6.
