What Are the Functions of Prostaglandin? Prostaglandins are hormone-like chemicals that synthesize within the cells of the human body. There are 10 known prostaglandin receptors located on various tissues that help process prostaglandins. The receptors allow prostaglandins to act on a wide range and type of cells. Prostaglandins have a short functional life and are either locally active or act on the same cell within which they are synthesized. The major types of prostaglandins include PGI2, PGE2 and PGF2?, each performing different functions.
