Leukotriene D5
leukotriene D5 is coverted from 5-hydroxy-6-S-glutathionyl-7,9,11,14,17-eicosapentaenoic acid (leukotriene C5) by gamma-glutamyl transpeptidase. Leukotrienes are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways. leukotriene D5 is coverted from 5-hydroxy-6-S-glutathionyl-7,9,11,14,17-eicosapentaenoic acid (leukotriene C5) by gamma-glutamyl transpeptidase
