Physicochemical Information
Prostaglandin B2 was found in human seminal plasma in an amout of 50 micrograms per ml as measured in combination with prostaglandins A1,A2 and B1 Bergstrom_S .
Prostaglandin E2 is converted to prostaglandin B2 non-enzymatically at alkaline condition Pike_JE et al.. Huma serum contains a dehydrase converting prostaglandin E2 to A2, an isomerase converting prostaglandin A2 to C2, and another isomerase converting prostaglandin C2 to B2 Polet_H et al..
