Application

γ-linolenic acid has been used as an analytical standard in gas chromatography. It may be used in nutritional studies regarding weight regain and as a possible tumor suppression agent. γ-linolenic acid is used in studies on the mechanisms and prevention of oxidation/peroxidation of unsaturated fatty acids.

Biochem/physiol Actions

γ-Linolenic acid , a polyunsaturated fatty acid, exerts anti-inflammatory effect by decreasing both interleukin (IL) 6 and IL-8 production in the human enterocyte-like cell line Caco-2 and humandendritic cells in vitro .
Gamma-linolenate (C18:6,9,12) differs from α-linolenate (C18:9,12,15) in the positions of the double bonds.

Considerable debate remains regarding the distinct biological activities of individual polyunsaturated fatty acids (PUFA). One of the most interesting yet controversial dietary approaches has been the possible prophylactic role of dietary gamma-linolenic acid (GLA) in treating various chronic disease states.
