About Vitamin B-12
The central structure of the vitamin consists of a single cobalt atom surrounded by four pyrrole rings. This set up is called 'Corrin Ring' system. This cobalt atom is in turn covalently bounded to a cyanide group. It is hence called cyanocobalamine.
Vitamin B-12 is required for the conversion of homocysteine to methionine which is processed by enzymes. Vitamin B12 deficiency, like folic acid deficiency, can cause increased homocysteine in the blood.
Vitamin B-12 and folate are both necessary for the synthesis of raw materials that make up the DNA.
