WebSecreted NO enters platelets where it activates the enzyme guanylate cyclase, which then stimulates the formation of cGMP (cyclic guanosine mono-phosphate). cGMP then blocks the function of phospholipase C. In the absence of NO, phospholipase C cleaves the membrane phospholipid PIP2, which leads to the production of inositol triphosphate (IP3). WebMar 13, 2024 · The first enzyme is phospholipase A2 (PLA2), which mediates the hydrolysis of the sn-2 position on phospholipid backbone, yielding a free AA molecule directly in one single step [19]. The second and the third enzymes are phospholipase C (PLC) and phospholipase D (PLD) that may also generate free AA (Fig. 3). billy mitchell leadership test
