Metabolite Identification
Common NameProstaglandin H2
DescriptionProstaglandin H2, also known as PGH2 or endoperoxide H2, belongs to the class of organic compounds known as prostaglandins and related compounds. These are unsaturated carboxylic acids consisting of a 20 carbon skeleton that also contains a five member ring, and are based upon the fatty acid arachidonic acid. Thus, prostaglandin H2 is considered to be an eicosanoid lipid molecule. Prostaglandin H2 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.

3. Prostaglandin-H2 D-isomerase
General function:
Involved in prostaglandin-D synthase activity
Specific function:
Catalyzes the conversion of PGH2 to PGD2, a prostaglandin involved in smooth muscle contraction/relaxation and a potent inhibitor of platelet aggregation. Involved in a variety of CNS functions, such as sedation, NREM sleep and PGE2-induced allodynia, and may have an anti-apoptotic role in oligodendrocytes. Binds small non-substrate lipophilic molecules, including biliverdin, bilirubin, retinal, retinoic acid and thyroid hormone, and may act as a scavenger for harmful hydrophobic molecules and as a secretory retinoid and thyroid hormone transporter. Possibly involved in development and maintenance of the blood-brain, blood-retina, blood-aqueous humor and blood-testis barrier. It is likely to play important roles in both maturation and maintenance of the central nervous system and male reproductive system (By similarity).
