Application Notes:
This product is the methyl ester of a naturally occurring omega-6 fatty acid that is found mainly in small amounts in animal
tissues. Eicosadienoic acid (all cis-11,14) is produced by a delta 9 elongase enzyme from linoleic acid and can be converted
into dihomo-gamma-linolenic acid, arachidonic acid, sciadonic acid and other polyunsaturated fatty acids.1 Eicosadienoic
acid (all cis-11,14) has been found to be able to modulate the metabolism of polyunsaturated fatty acids and alter the
responsiveness of macrophages to inflammatory stimulations.2 Along with other mono and polyunsaturated fatty acids
eicosadienoic acid (all cis-11,14) can inhibit the binding of leukotriene B4 to pig neutrophil membranes, which may account
in part for it’s anti-inflammatory activities.3 The X-ray powder diffraction pattern of the sodium soap of eicosadienoic acid
(all cis-11,14) is typical of the crystalline lamellar phase.4
