The Uses of 17-OCTADECYNOIC ACID
17-ODYA (17-Octadecynoic acid) is a potent suicide inhibitor of LTB4 ω-oxidase.
Definition
ChEBI: Octadec-17-ynoic acid is an acetylenic fatty acid that is octadecanoi acid (stearic acid) which has been doubly dehydrogenated at positions 17 and 18 to give the corresponding alkynoic acid. It has a role as a P450 inhibitor, an EC 1.14.14.94 (leukotriene-B4 20-monooxygenase) inhibitor and an EC 1.14.15.3 (alkane 1-monooxygenase) inhibitor. It is a long-chain fatty acid, an acetylenic fatty acid, a terminal acetylenic compound and a monounsaturated fatty acid.
