arachidonic acid
BiochemistryA 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). Arachidonic acid release from phospholipids is the limiting step in forming its active metabolites.
Nutrition
