Prostaglandin E2 1-glyceryl ester is a 1-monoglyceride resulting from the condensation of the carboxy group of prostaglandin E2 with the 1-hydroxy group of glycerol. It has a role as a human metabolite. It is a 1-monoglyceride, an alicyclic ketone, a prostaglandins E, a tetrol and a secondary allylic alcohol. It derives from a prostaglandin E2.

2-Arachidonoyl glycerol (2-AG; ) has been isolated from porcine brain, and has been characterized as the natural endocannabinoid ligand for the CB1receptor.1,2Incubation of 2-AG with cyclooxygenase-2 and specific prostaglandin H2(PGH2) isomerases in cell cultures and isolated enzyme preparations results in prostaglandin glycerol ester formation.3The biosynthesis of PGH, PGD, PGE, PGF, and Thromboxane A-2-glyceryl ester compounds have all been documented. The 2-glyceryl ester moiety equilibrates rapidly (within minutes) with the more stable 1-glyceryl ester, producing a 10:90 2:1-glyceryl ester mixture in typical aqueous media. While the stability and metabolism of these prostaglandin products has been investigated, little is known about their intrinsic biological activity.4

Prostaglandin E2-1-glyceryl ester-d5 (PGE2-1-glyceyl ester-d5) is deuterium labeled Prostaglandin E2-1-glyceryl ester. Prostaglandin E2-1-glyceryl ester, a Prostaglandin Glycerol Ester, is an endocannabinoid ligand for the CB1 receptor. Prostaglandin E2-1-glyceryl ester induces rapid, transient elevation of intracellular free Ca2+[1][2].
