Explanation:
Detailed explanation-1: -Vitamin B12 is involved in cellular metabolism in two active coenzyme forms-methylcobalamin and 5-deoxyadenosylcobalamin. Vitamin B12 cooperates with folic acid (folate) in the synthesis of deoxyribonucleic acid (DNA).
Detailed explanation-2: -Thus, vitamin B-12 is important for DNA synthesis, regenerating methionine for protein synthesis and methylation, and preventing homocysteine accumulation (1).
Detailed explanation-3: -All of the water-soluble vitamins and two of the fat-soluble vitamins, A and K, function as cofactors or coenzymes. The active forms of riboflavin, vitamin B2, are the coenzymes flavin mononucleotide (FMN; Figure 2) and flavin adenine dinucleotide (FAD). More items
