Detailed explanation-1: -In essence, the B-complex vitamins act as coenzymes in energy metabolism. The B complex of vitamins includes thiamin (vitamin Bl), riboflavin (vitamin B2), niacin, vitamin B6 (pyridoxine), folate (folic acid), vitamin B12 (cobalamin), pantothenic acid, and biotin.
Detailed explanation-2: -Like all Vitamin B’s, Vitamin B1 (Thiamine) is involved in the energy production system of the body. Vitamin B1 operates in the initial stage of cellular respiration enabling the breakdown of glucose into carbon dioxide and water.
Detailed explanation-3: -Vitamin B-12 is a cofactor for 2 enzymes. In the cytoplasm, methionine synthase requires vitamin B-12 in the form of methylcobalamin and catalyzes the conversion of homocysteine to methionine by transfer of a methyl group from methyltetrahydrofolate.
Detailed explanation-4: -Vitamins. All of the water-soluble vitamins and two of the fat-soluble vitamins, A and K, function as cofactors or coenzymes.
