Metabolite Identification
Common Name8(S)-HPETE
Description8S-HPETE is metabolized from arachidonic acid by the enzyme 8S-lipoxygenase (8-LOX in mouse, ALOX15 and ALOX15B in human). 8S-HPETE will be readily reduced under physiological circumstances to 8S-hydroxyeicosatetraenoic acid (8S-HETE), a natural agonist of peroxisome proliferator-activated receptor alpha (PPAR alpha).
