Common NameHydroxycobalamin
DescriptionVitamin (haematopoietic) A B 12 vitamin. It has been used therapeutically in the treatment and prevention of vitamin B 12 deficiency. -- Pubchem; Hydroxocobalamin (OHCbl) is a natural analog of vitamin B-12, a basic member of the cobalamin family of compounds. It has an intense red color. Vitamin B12 is a term that refers to a group of compounds called cobalamins that are available in the human body in a variety of mostly interconvertible forms. Together with folic acid, cobalamins are essential cofactors required for DNA synthesis in cells where chromosomal replication and division are occurring?Most notably the bone marrow and myeloid cells. As a cofactor, cobalamins are essential for two cellular reactions: (1) The mitochondrial methylmalonylcoenzyme A mutase conversion of methylmalonic acid (MMA) to succinate, which links lipid and carbohydrate metabolism, and (2) activation of methionine synthase, which is the rate limiting step in the synthesis of methionine from homocysteine and tetrahydrofolate (Katzung, 1989).; Hydroxocobalamin is a synthetic, injectable form of Vitamin B12. Hydroxocobalamin is actually a precursor of two cofactors or vitamins (Vitamin B12 and Methylcobalamin) which are involved in various biological systems in man. Vitamin B12 is required for the conversion of methylmalonate to succinate. Deficiency of this enzyme could therefore interfere with the production of lipoprotein in myelin sheath tissue and so give rise to neurological lesions. The second cofactor, Methylcobalamin, is necessary for the conversion of homocysteine to methionine which is essential for the metabolism of folic acid. Deficiency of tetrahydrafolate leads to reduced synthesis of thymidylate resulting in reduced synthesis of DNA which is essential for cell maturation. Vitamin B12 is also concerned in the maintenance of sulphydryl groups in reduced form, deficiency leading to decreased amounts of reduced SH content of erythrocytes and liver cells. Overall, vitamin B12 acts as a coenzyme for various metabolic functions, including fat and carbohydrate metabolism and protein synthesis. It is necessary for growth, cell replication, hematopoiesis, and nucleoprotein as well as myelin synthesis. This is largely due to its effects on metabolism of methionine folic acid, and malonic acid.
