Linoleic acid (LA) is an organic compound with the formula HOOC(CH2)7CH=CHCH2CH=CH(CH2)4CH3. Both alkene groups (−CH=CH−) are cis. It is a fatty acid sometimes denoted 18:2 (n−6) or 18:2 cis-9,12. A linoleate is a salt or ester of this acid.[5]

Linoleic acid is a polyunsaturated, omega−6 fatty acid. It is a colorless liquid that is virtually insoluble in water but soluble in many organic solvents.[2] It typically occurs in nature as a triglyceride (ester of glycerin) rather than as a free fatty acid.[6] It is one of two essential fatty acids for humans, who must obtain it through their diet,[7] and the most essential, because the body uses it as a base to make the others.

The word "linoleic" derives from Latin linum 'flax' and oleum 'oil', reflecting the fact that it was first isolated from linseed oil.

History

[edit]

In 1844, F. Sacc, working at the laboratory of Justus von Liebig, isolated linoleic acid from linseed oil.[8][9] In 1886, K. Peters determined the existence of two double bonds.[10] Its essential role in human diet was discovered by G. O. Burr and others in 1930.[11] Its chemical structure was determined by T. P. Hilditch and others in 1939, and it was synthesized by R. A. Raphael and F. Sondheimer in 1950.[12]

In physiology

[edit]
Main articles: Fatty acid desaturase and Fatty acid synthesis

The consumption of linoleic acid is vital to proper health, as it is an essential fatty acid.[13]

Metabolism and eicosanoids

[edit]

Linoleic acid (LA: C
18H
32O
2; 18:2,n−6) is a precursor to arachidonic acid (AA: C
20H
32O
2; 20:4,n−6) with elongation and unsaturation.[13] AA is the precursor to some prostaglandins,[14] leukotrienes (LTA, LTB, LTC), thromboxane (TXA)[15] and the N-acylethanolamine (NAE) arachidonoylethanolamine (AEA: C
22H
37NO
2; 20:4,n−6),[16] and other endocannabinoids and eicosanoids.[17]

The metabolism of LA to AA begins with the conversion of LA into gamma-linolenic acid (GLA), effected by Δ6 desaturase.[18] GLA is converted to dihomo-γ-linolenic acid (DGLA), the immediate precursor to AA.

LA is also converted by various lipoxygenases, cyclooxygenases, cytochrome P450 enzymes (the CYP monooxygenases), and non-enzymatic autoxidation mechanisms to mono-hydroxyl products viz., 13-Hydroxyoctadecadienoic acid, and 9-Hydroxyoctadecadienoic acid; these two hydroxy metabolites are enzymatically oxidized to their keto metabolites, 13-oxo-octadecadienoic acid and 9-oxo-octadecdienoic acid. Certain cytochrome P450 enzymes, the CYP epoxygenases, catalyze oxidation of LA to epoxide products viz., its 12,13-epoxide, vernolic acid, and its 9,10-epoxide, coronaric acid. These linoleic acid products are implicated in human physiology and pathology.[19]

Hydroperoxides derived from the metabolism of anandamide (AEA: C
22H
37NO
2; 20:4,n−6), or its linoleoyl analogues, are by a lipoxygenase action found to be competitive inhibitors of brain and immune cell FAAH, the enzyme that breaks down AEA and other endocannabinoids, and the compound linoleoyl-ethanol-amide (C
20H
37NO
2; 18:2,n−6), an N-acylethanolamine,[clarification needed] - the ethanolamide of linoleic acid (LA: C
18H
32O
2; 18:2,n−6) and its metabolized incorporated ethanolamine (MEA: C
2H
7NO),[20] is the first natural inhibitor of FAAH, discovered.[21][22]

Uses and reactions

[edit]

Linoleic acid is a component of quick-drying oils, which are useful in oil paints and varnishes. These applications exploit the lability of the doubly allylic C−H groups (−CH=CH−CH2−CH=CH−) toward oxygen in air (autoxidation). Addition of oxygen leads to crosslinking and formation of a stable film.[23]

Reduction of the carboxylic acid group of linoleic acid yields linoleyl alcohol.[24]

Linoleic acid is a surfactant with a critical micelle concentration of 1.5 x 10−4 M @ pH 7.5.[citation needed]

Linoleic acid has become increasingly popular in the beauty products industry because of its beneficial properties on the skin. Research points to linoleic acid's anti-inflammatory, acne reductive, skin-lightening and moisture retentive properties when applied topically on the skin.[25][26][27][28]

Linoleic acid is also used in some bar of soap products.

Other occurrences

[edit]

Cockroaches release oleic and linoleic acid upon death, which discourages other roaches from entering the area. This is similar to the mechanism found in ants and bees, which release oleic acid upon death.[59]

Health effects

[edit]

Consumption of linoleic acid has been associated with lowering the risk of cardiovascular disease, diabetes and premature death.[60][61][62] There is high-quality evidence that increased intake of linoleic acid decreases total blood cholesterol and low-density lipoprotein.[63]

The American Heart Association advises people to replace saturated fat with linoleic acid to reduce CVD risk.[64]
