γ-リノレン酸メチル

説明Polyunsaturated fatty acids (PUFAs) are essential nutrients that show distinct deficiency syndromes when not present in adequate amounts in the diet. γ-Linolenic Acid methyl ester (Methyl GLA) is an esterified version of the free acid which is less water soluble but more amenable for the formulation of GLA-containing diets and dietary supplements. GLA is an ω-6 fatty acid which can be elongated to arachidonic acid for endogenous eicosanoid synthesis. It is a weak leukotriene B4 (LTB4) receptor antagonist, inhibiting [3H]-LTB4 binding to porcine neutrophil membranes with a Ki of 1 μM. GLA produces 53% inhibition at a 1 mg/kg dose in an in vivo model of LTB4-induced bronchoconstriction.

使用Methyl γ-linolenate may be used as an analytical standard for the determination of aldehydes such as pentanal and hexanal via peroxidation, further analyzed by gas chromatography technique. It may also be used as an analytical reference standard for the quantification of the analyte in serum lipid extract and Arthrospira (Spirulina) platensis using the gas-chromatography technique.
