Source	In most animal tissues prostanoids are synthesized enzymatically de novo upon physiological and pathological stimulations, and this is also the case of prostaglandin D2. Prostaglandin D2 is produced in barin, lung, spleen, mast cells and other tissues Urade_Y et al..
Chemical Synthesis	Hayashi_M et al.
Metabolism	Prostaglandin D2 is produced by isomerization of 9,11-endoperoxide of prostaglandin H2. There are two isozymes of prostaglandin D synthase (hematopoietic type and lipocalin type) distinguished by glutathione reequirement and effect of inhibitor Urade_Y et al.. Prostaglandin D2 is either reduced to 9a,11b-prostaglandin F or oxidized to 15-keto-prostaglandin D2 by a specific dehydrogenase Giles_H et al.. Non-enzymatic transformation of prostaglandin D2 produces anti-neoplastic D12-prostaglandin J2 Negishi_M et al..
