A common metabolic pathway for several prostaglandins (PGs), including PGD₂, involves the reduction of the double bond between C-13 and C-14 and oxidation of the hydroxyl group at C-15, producing 13,14-dihydro-15-keto PGs. The removal of four carbons at the α-terminus and oxidation of the terminal ω-carbon produces the abundant urinary metabolites, including tetranor-PGDM. 13,14-dihydro-15-keto-tetranor PGD₂ is a potential metabolite of PGD₂. It would be produced from the known metabolite 13,14-dihydro-15-keto PGD₂ , which is a known agonist for the CRTH2/DP₂ receptor.

ChEBI: 13,14-dihydro-15-keto-tetranor Prostaglandin D2 is a member of cyclopentanols.
