Chemical Structure:

Vitamin B12 is the name for a class of chemically-related compounds, all of which have vitamin activity. It is structurally the most complicated vitamin with a collection of cobalt and corrin ring, only bacteria have the enzymes required for its synthesis.
Vitamin B12 is important for the normal functioning of the brain, nervous system and for the formation of blood. It is normally involved in the metabolism of every cell of the body, especially affecting DNA synthesis and regulation, fatty acid synthesis and energy production.
A common form of the vitamin B12, cyanocobalamin, is deeply red colored, easy to crystallize, and is not sensitive to air-oxidation, it is typically used as a supplement and food additive.
The main syndrome of vitamin B-12 deficiency is Biermer's disease (pernicious anemia).
Vitamin B-12 is naturally found in meat (especially liver and shellfish), milk and eggs.

(many of the functions of Vitamin B12 can be replaced by sufficient quantities of folic acid (another B vitamin), since Vitamin B12 is used to regenerate folate in the body. Most " Vitamin B12 deficient symptoms" are actually folate deficient symptoms, since they include all the effects of pernicious anemia and megaloblastosis, which are due to poor synthesis of DNA when the body does not have a proper supply of folic acid for the production of thymine.)
