Vitamin B12 is converted in to coenzyme B12 in the tissues which is essential for conversion of methyl-malonate to succinate and synthesis of methionine from homocystine. It is also associated with fat and carbohydrate metabolism and protein synthesis. Cells characterized by rapid division such as epithelial cells, bone marrow, and myeloid cells appear to have greatest requirement of Cyanocobalamin.Pharmacokinets of Vit B12Absorption: Absorbed irregularly after oral administration and absorption depends on Ca and intrinsic factor. It is also administered subcutaneously and intramuscularly.
Distribution: Distributed in to liver, bone marrow, and other tissues. It crosses the placenta and appears in breast milk.
