Elaidic acid is a monounsaturated trans fatty acid and the 9-trans isomer of oleic acid that has been found in partially hydrogenated cooking oils.1 It reduces HHT and HETE formation and increases synthesis of prostaglandin E2 , PGF2α , PGD2 , and thromboxane B2 induced by arachidonic acid in isolated human platelets. Elaidic acid (0.1-5 mmol/L) induces apoptosis in human umbilical vein endothelial cells (HUVECs).2 In vivo, elaidic acid (100 mg/kg) reduces cardiac and hepatic autophagy induced by palmitic acid in mice.3
