15(S)-HEPE-d5 ethyl ester

15(S)-HEPE-d5 ethyl ester is intended for use as an internal standard for the quantification of 15-HEPE ethyl ester by GC- or LC-MS. 15(S)-HEPE ethyl ester is an esterified form of the monohydroxy fatty acid 15(S)-HEPE (Cay-32710). 15(S)-HEPE is biosynthesized from eicosapentaenoic acid (EPA, Cay-90110, Cay-90110.1, Cay-21908) by 15-lipoxygenase (15-LO). 15(R)-HEPE is formed by aspirin-acetylated COX-2-mediated oxidation of EPA.Formal Name: 15(S)-hydroxy-5Z,8Z,11Z,13E,17Z-eicosapentaenoic-19,19,20,20,20-d5 acid, ethyl ester.
