Vitamin B-12

About Vitamin B-12
RSS Feeds   Text 
This Vitamin is also known as cobalamine or cyanocobalamine, owing to the presence of the metal, cobalt. Cyanocobalamine is used in most supplements because it is readily converted to active forms of vitamin B-12 in the body.




Vitamin B12

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.
