Hemolytic anemia is associated with a deficiency of which of the following vitamins?: (A) Vitamin D, (B) Vitamin K, (C) Vitamin C, (D) Vitamin E
Answer is D. The most impoant function of vitamin E, is its chain-breaking antioxidant role in the prevention of the non-enzymatic oxidation of cell components, such as the peroxidation of polyunsaturated fatty acids by free radicals. In vitamin E deficiency, there is no prevention of the lipid peroxidation caused due to free radicals. the erythrocyte membranes are rendered abnormally fragile leading to hemolytic anemia.
