Metabolite Identification
Common Name11(R)-HPETE
Description11R-HPETE is a hydroperoxyeicosatetraenoic acid eicosanoid derived from arachidonic acid. 11R-HPETE is formed from arachidonic acid in the prostaglandin endoperoxide H synthase-1 cyclooxygenase site. 11R-HPETE has been described in other mammalian tissues (rat, sheep). There are two distinct isozymes of prostaglandin H synthase (PGHS), the key enzyme in prostaglandin biosynthesis; PGHS-1 is generally considered to play a housekeeping role, whereas PGHS-2 has been linked to various pathological processes. Both PGHS isozymes have two catalytic activities; they are a cyclooxygenase activity that converts arachidonic acid (AA) to prostaglandin G2 (PGG2) and a peroxidase activity that catalyzes the transformation of PGG2 to prostaglandin H2. Oxygenase activity is completely abolished in aspirin-treated PGHS-1 (ASA-PGHS-1), whereas aspirin-treated PGHS-2 (ASA-PGHS-2) still catalyzes formation of 11(R)-HPETE.
