17(S)-HDHA-d5

17(S)-HDHA-d5 is intended for use as an internal standard for the quantification of 17(S)-HDHA by GC- or LC-MS. (±)17-HDHA is formed via autooxidation of docosahexaenoic acid (DHA, Cay-90310, Cay-17950). 17(S)-HDHA is formed from DHA by 15-lipoxygenase (15-LO) and is a precursor in the formation of 17(S)-resolvin D1 (Cay-10012554). 17(R)-HDHA is formed by aspirin-acetylated COX-2-mediated oxidation of DHA and is a precursor in the formation 17(R)-resolvin D1 (Cay-13060).Formal Name: 17(S)-hydroxy-4Z,7Z,10Z,13Z,15E,19Z-docosahexaenoic-21,21,22,22,22-d5 acid.
