(d) Vitamin B_12/विटामिन B_12
Show Answer
S15. Ans.(d)
Sol. Vitamin B_12 (Cyanocobalamin) is a water soluble vitamin. It contains a metallic ion cobalt. Its chemical formula is C_63 H_88 Co N_14 O_14 P. It functions as a cofactor for enzymes in the metabolism of amino acids and fatty acids, required for new cell synthesis, normal blood formation and neurological function. Its deficiency causes pernicious anaemia, nervous symptoms etc.
