Linoleic acid is a naturally occurring omega-6 essential fatty acid, present in a variety of foods, including the oils. Linoleic acid is a precursor for arachidonic acid biosynthesis; on the first enzymatic step of the pathway involves delta-6-desaturase, which converts linoleic acid to gamma-lenolenic acid. Linoleic acid has beneficial effects on human skin and hair. Replacement of saturated fat with linoleic acid is advocated to improve serum lipoprotein profiles and reduce the risk of coronary artery disease. Linoleic acid was tested in clinical trilas as a possible remedy against multiple sclerosis.
