Source	Prostaglandin E2 was found to be accummulating in human semen in an amount of about 13 microgram per ml Bergstrom_S ;>. In most animal tissues prostanoids are synthesized enzymatically de novo upon physiological and pathological stimulations, and this is also the case of prostaglandin E2.
Chemical Synthesis	File:XPR1401FT0001.gif Corey_EJ et al.;>
Metabolism	Prostaglandin E2 is produced from arachidonic acid via prostaglandins G2 and H2 by the catalyses of prostaglandin endoperoxide synthase (cyclooxygenase) Smith_WL et al.;> and prostaglandin E synthase Urade_Y et al.;>. Two isoforms of the cyclooxygnease enzyme responsible for prostaglandin H2 synthesis are present. Cyclooxygenase-1 is constitutively found in most mammalian tissues, while cyclooxygnease-2 is induced rapidly and transiently in physiological and pathological events, especially in inflammation Smith_WL et al.;>. The biological activities of prostaglandin E2 are lost by oxidation of its 15-hydroxyl group catalyzed by 15-hydroxyprostaglandin dehydrogenase Hansen_HS ;>.
