17(S)-HDHA-d5 ethyl ester

17(S)-HDHA-d5 ethyl ester is intended for use as an internal standard for the quantification of 17-HDHA ethyl ester by GC- or LC-MS. 17(S)-HDHA ethyl ester is an esterified form of the hydroxy fatty acid and docosahexaenoic acid (DHA, Cay-90310, Cay-17950) 15-lipoxygenase (15-LO) metabolite 17(S)-HDHA (Cay-10009799). (±)17-HDHA is an autoxidation product of DHA, and 17(R)-HDHA is formed by aspirin-acetylated COX-2-mediated oxidation of DHA.Formal Name: 17(S)-hydroxy-4Z,7Z,10Z,13Z,15E,19Z-docosahexaenoic-21,21,22,22,22,22-d5, ethyl ester. Synonyms: 17(S)-hydroxy DHA-d5 ethyl ester, 17(S)-hydroxy Docosahexaenoic Acid-d5 ethyl ester, 17(S)-HDoHE-d5 ethyl ester. Molecular Formula: C24H31D5O3. Formula Weight: 377.6.
