    Product Description

    11(E)-Eicosenoic acid is a very long-chain ω-9 fatty acid that is a trans monounsaturated isomer of arachidic acid (Item No. 9000339). 11(E)-Eicosenoic acid is one of several monounsaturated 20-carbon fatty acids.1 The combined C20:1 isomers constitute 70% of the total fatty acid pool in jojoba seed oil isolated from plants in the Arizona desert. Unlike other eicosenoic fatty acids, 11(E)-eicosenoic acid does not inhibit leukotriene B4 (Ki = 1,150 µM in a radioligand binding assay in pig neutrophil membranes) or affect telomerase activity.2,3
