Notes: 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; Item Nos. 90310 / 17950) 15-lipoxygenase (15-LO) metabolite 17(S)-HDHA (Item No. 10009799). (±)17-HDHA is an autoxidation product of DHA, and 17(R)-HDHA is formed by aspirin-acetylated COX-2-mediated oxidation of DHA.{7479,7491,68191}
