Methyl (13Z,16Z,19Z) -docosatrienoate

Cis-13,16,19-Docosatrienoic acid methyl ester is an ester form of docosatrienoic acid, a rare ?-3 fatty acid. This compound is not easily detectable in the normal phospholipid polyunsaturated fatty acid pool and at a concentration of 5 ?M, it inhibits the binding of [3H]-LTB4 to porcine neutrophils. The methyl ester form exhibits greater lipid solubility than the free acid, potentially making it more suitable for certain formulations.
