Arachidonic Acid

Arachidonic acid is a long-chain fatty acid that is a C20, polyunsaturated fatty acid having four (Z)-double bonds at positions 5, 8, 11 and 14. It has a role as a mouse metabolite, a human metabolite, an EC 3.1.1.1 (carboxylesterase) inhibitor and a Daphnia galeata metabolite. It is a long-chain fatty acid, an omega-6 fatty acid and an icosa-5,8,11,14-tetraenoic acid. It is a conjugate acid of an arachidonate. It derives from a hydride of a (5Z,8Z,11Z,14Z)-icosa-5,8,11,14-tetraene. — ChEBI
