Physicochemical Information | |
Prostaglandin G2 is produced by bis-dioxygenation and cyclization of arachidonic acid as an intermediate for the biosyntheses of various prostaglandins and thromboxanes. The responsible enzyme is prostaglandin endoperoxide synthase usually referred to as fatty acid cyclooxygenase, and distributed in various animal tissues . | |
Prostaglandin endoperoxide synthase is a bifunctional enzyme with an oxygenase activity (fatty acid cyclooxygenase) producing prostaglandin G2 from arachidonic acid and a peroxidase activity (prostagladnin hydroperoxidase) converting prostaglandin G2 to prostaglandin H2 .
