In 1886, K. Peters determined the existence of two double bonds.
Its essential role in human diet was discovered by G. O. Burr and others in 1930.
C18:2 Linoleic Acid's 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.
In physiology
The consumption of C18:2 Linoleic Acid is vital to proper health, as it is an essential fatty acid.
Metabolism and eicosanoids
C18:2 Linoleic Acid (LA: C18H32O2; 18:2,n−6) is a precursor to arachidonic acid (AA: C20H32O2; 20:4,n−6) with elongation and unsaturation.
AA is the precursor to some prostaglandins, leukotrienes (LTA, LTB, LTC), thromboxane (TXA) and the N-acylethanolamine (NAE) arachidonoylethanolamine (AEA: C22H37NO2; 20:4,n−6), and other endocannabinoids and eicosanoids.
The metabolism of C18:2 Linoleic Acid to AA begins with the conversion of LA into gamma-linolenic acid (GLA), effected by Δ6 desaturase.
GLA is converted to dihomo-γ-linolenic acid (DGLA), the immediate precursor to AA.
C18:2 Linoleic Acid 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 C18:2 Linoleic Acid to epoxide products viz., its 12,13-epoxide, vernolic acid, and its 9,10-epoxide, coronaric acid.
These C18:2 Linoleic Acid products are implicated in human physiology and pathology.
Hydroperoxides derived from the metabolism of anandamide (AEA: C22H37NO2; 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.
The compound linoleoyl-ethanol-amide (C20H37NO2; 18:2,n−6), an N-acylethanolamine, the ethanolamide of C18:2 Linoleic Acid (LA: C18H32O2; 18:2,n−6) and its metabolized incorporated ethanolamine (MEA: C2H7NO), is the first natural inhibitor of FAAH, discovered.
SAFETY & USAGE of C18:2 LINOLEIC ACID:
C18:2 Linoleic Acid is generally regarded as safe for dietary and cosmetic use when consumed or applied at typical levels found in foods and products.
As with other fatty acids, concentrated pure C18:2 Linoleic Acid does not typically pose acute toxicity risks under normal handling.
Some safety data sheets note no classification under EU CLP hazard criteria when handled under good occupational hygiene practices, and C18:2 Linoleic Acid is not inherently flammable or corrosive under ordinary conditions.
However, oxidized or degraded C18:2 Linoleic Acid (exposed to heat or air for long periods) may generate peroxides or rancid products that can irritate skin or mucous membranes.
In high-concentration laboratory scenarios, standard precautionary measures (gloves, goggles, adequate ventilation) are recommended.
C18:2 Linoleic Acid does not bioaccumulate significantly and is biodegradable, reflecting its metabolic role in biological systems.
Users with specific health considerations or working in industrial contexts should consult relevant safety data sheets (SDS) for detailed hazard statements, first-aid measures, and storage guidelines tailored to the grade and form of C18:2 Linoleic Acid they are using.
