20 hydroxy prostaglandin e2

20-hydroxy Prostaglandin E2 (20-hydroxy PGE2) is a product of cytochrome P450 metabolism of PGE2 . ω-Oxidation at C-20 followed by β-oxidation and the loss of up to four carbons from the lower side chain is a prominent metabolic pathway for PGE2. 20-hydroxy PGE2 is the putative first intermediate in this chain of chemical transformations.
