Aspects of Prostaglandin Glycerol Ester Biology.Adv Exp Med Biol. 2019; 1161:77-88.AE
The Cyclooxygenase enzymes (COX-1 and COX-2) incorporate 2 molecules of O2 into arachidonic acid (AA), resulting in an array of bioactive prostaglandins. However, much work has been done showing that COX-2 will perform this reaction on several different AA-containing molecules, most importantly, the endocannabinoid 2-arachidonoylglycerol (2-AG). The products of 2-AG oxygenation, prostaglandin glycerol esters (PG-Gs), are analogous to canonical prostaglandins. This chapter reviews the literature detailing the production, metabolism, and bioactivity of these compounds, as well as their detection in intact animals.
