Vitamin E is responsible for all the following Except: (A) It prevents lipid peroxidation in biological membrances, (B) It prevents RBC from hemolysis, (C) It is considered to be anti-sterility vitamin, (D) It ours the oxidation of low-density lipoproteins
Answer is D. The main function of vitamin E is as a chain-breaking, free-radical-trapping antioxidant in cell membranes and plasma lipoproteins by reacting with the lipid peroxide radicals formed by peroxidation of polyunsaturated fatty acids.In experimental animals, vitamin E deficiency results in resorption of fetuses and testicular atrophy. The erythrocyte membranes are abnormally fragile as a result of lipid peroxidation, leading to hemolytic anaemia.Harper 30th edition Pg 553
