Prostaglandins are one group of eicosanoids. They are unsaturated fatty acids derivatives that are involved in the contraction of smooth muscle, the control of homeostatic activities such as, inflammation and body temperature, and many more functions of the body. Prostaglandins are derived from arachidonic acid. The formation of the both the arachidonic acid, then prostaglandin molecules begins with a stimulus to a cell, that activates a membrane enzyme called phospholipase A2. The arachidonic acid metabolized from the phospholipase is now the substrate for one enzyme during the process of production . The enzyme cyclooxygenase or (COX) transforms the arachidonic acid. The product of this reaction continues to go through an enzymatic reaction
