Metabolite Identification
Common Name8(S)-HPETE
Description8(S)-HPETE, also known as 8-HPETE, belongs to the class of organic compounds known as hydroperoxyeicosatetraenoic acids. These are eicosanoic acids with an attached hydroperoxyl group and four CC double bonds. Thus, 8(S)-hpete is considered to be an eicosanoid. Based on a literature review very few articles have been published on 8(S)-HPETE.
