In mammals, arachidonic acid is synthesized from linoleic acid. Biochemistry. A polyunsaturated omega-6 fatty acid, which is an essential dietary component for mammals and the precursor for biosynthesis of prostaglandins, thromboxanes and hydroxy-eicosatetraenoic acid derivatives (e.g., leukotrienes). polyunsaturated omega-6 fatty acid, which is an essential dietary component for mammals and the precursor for biosynthesis of prostaglandins, thromboxanes and hydroxy-eicosatetraenoic acid derivatives (e.g., leukotrienes).
Arachadonic acid is released from the platelet cell membrane by phospholipaseand then rapidly oxidized by the enzyme cyclo oxygenase to PGG 2 & PGH 2 In the platelets:PGG 2 is converted to TX A 2 a highly potent platelet aggregator and constrictor of arterial muscle In the arterial endothelium: PGG 2 & PGH
