"DGL-CoA (8,11,14-eicosatrienoyl-CoA) undergoes desaturation by delta 5-desaturase (D5-desaturase) forming arachidonoyl-CoA (AA-CoA, 5,8,11,14-Eicosatetraenoic acid). D5-desaturase has 62% sequence identity with D6-desaturase but desaturates a different carbon atom, adding a double bond at position C5 in arachidonoyl-CoA (AA-CoA). AA can be metabolized by variety of oxygenases (including cyclo-oxygenase and lipoxygenase systems) to form a family of varying products known as eicosanoids, prostaglandins, leukotrines and thromboxanes thus playing important role in inflamation response."^^ . . . . . . .
