Prostaglandin G2 is an organic peroxide belonging to the family of prostaglandins.[1] The compound has been isolated as a solid, although it is usually used in vivo. It quickly converts into prostaglandin H2, a process catalyzed by the enzyme COX.

Prostaglandin G2 is produced from the fatty acid arachidonic acid. The reaction, a double oxygenation, requires the enzyme cyclooxygenase, which inserts two molecules of O2 into the C-H bonds of the substrate acid.[2][1][3]
