Natural Product Identification
Common Name12-hpete
Description12(S)-HPETE, also known as 12-hpete or omega-9 hpaa, 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, 12(S)-hpete is considered to be an eicosanoid lipid molecule. The (S)-enantiomer of 12-HPETE. 12(S)-HPETE is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 12(S)-HPETE exists in all living organisms, ranging from bacteria to humans. 12-hpete is found in Hydra vulgaris and Mus musculus. 12-hpete was first documented in 2002 (PMID: 12011469). In humans, 12(S)-hpete is involved in mefenamic acid action pathway.
