Mechanism of action for steroid hormones, vitamins and eicosanoids. These stimuli activate phospholipases in the cell membrane or cytoplasm, and arachidonic acid (a tetraenoic [4 double bonds] fatty acid) is released from membrane phospholipids (Figure 18–1).Arachidonic acid is then metabolized by several different enzymes. The primary precursor of the prostaglandins and other related eicosanoids is the Arachidonic acid, containing 20 carbons. Arachidonic acid is primarily the constituent of cell membrane phospholipids, mainly found in phosphatidylinositol and in other complex forms of lipid.
