Linoleic acid is a PUFA prevalent in the western diet. The peroxide free linoleic acid is protected from autoxidation by the antioxidant BHT (2,6-Di-tert-butyl-4-hydroxytoluene). Linoleic acid is also available without BHT (Item No. 90150).

Linoleic acid is an essential fatty acid and one of the most abundant PUFAs in the western diet. Deficiencies in linoleic acid are linked to defective wound healing, growth retardation, and dermatitis. Linoleic acid is metabolized by 15-LO in both plants and animals to form 9- and 13-HODE.
