Description
11,14,17-Eicosatrienoic acid (CAS 17046-59-2), also known as ETA, ETE, Icosatrienoic Acid, and Homo-alpha-linolenic acid, is a 20-carbon polyunsaturated omega-3 fatty acid. It is the direct chain-elongation product of alpha-linolenic acid and serves as a biochemical precursor in fatty acid metabolism pathways.
In pharmaceutical and nutraceutical formulations, ETA is studied for its role in modulating eicosanoid biosynthesis, where it competes with arachidonic acid at key enzymatic steps. In personal care applications, its polyunsaturated structure supports lipid barrier function and provides moisturizing activity through integration into skin lipid matrices.
ETA is supplied as a liquid fatty acid, handled under inert atmosphere to preserve integrity. Procurement should confirm REACH registration status and supplier documentation for intended use in food, feed, or cosmetic applications. Packaging is typically in sealed containers under nitrogen to minimise oxidative degradation during storage and transit.
