Biosynthesis of eicosanoids
WebJun 9, 2024 · This power point presentation explains the metabolism of eicosanoids i.e., the anabolism and catabolism separately. eicosanoids which are metabolites of dietary fatty acids and lipid metabolism, are basically paracrine hormones which act on neighboring target cells, and are quickly inactivated by self catalyzed enzymes. priscilla samuel. Follow. WebIn mammalian cells, eicosanoid biosynthesis is usually initiated by the activation of phospholipase A2 and the release of arachidonic acid (AA) from membrane …
