Vitamin B12

Vitamin B12 is a member of the vitamin B complex. It contains cobalt, and so is also known as cobalamin. It is exclusively synthesised by bacteria and is found primarily in meat, eggs and dairy products. There has been considerable research into proposed plant sources of vitamin B12. Fermented soya products, seaweeds, and algae such as spirulina have all been suggested as containing significant B12. However, the present consensus is that any B12 present in plant foods is likely to be unavailable to humans and so these foods should not be relied upon as safe sources. Many vegan foods are supplemented with B12. Vitamin B12 is necessary for the synthesis of red blood cells, the maintenance of the nervous system, and growth and development in children. Deficiency can cause anaemia. Vitamin B12 neuropathy, involving the degeneration of nerve fibres and irreversible neurological damage, can also occur.

Description of Vitamin B12 :

The term vitamin B12 (cobalamin) is used in two different ways. Vitamin B12 , a member of the B-vitamin family, is a collective term for a group of cobalt-containing compounds known as corrinoids. The principal cobalamins are cyanocobalamin, hydroxocobalamin and the two coenzyme forms of vitamin B12 , methylcobalamin and 5-deoxyadenosylcobalamin (adenosylcobalamin). The term vitamin B12 is more commonly used to refer to only one of these forms, cyanocobalamin. Cyanocobalamin is the principal form of the vitamin used for fortification of foods and in nutritional supplements. In this monograph, vitamin B12 will be used in both ways. The meaning will be clear from its context. The cobalamins are comprised of a nucleotide (base, ribose and phosphate) attached to a corrin ring. The corrin ring is made up of four pyrrole groups and an atom of cobalt in its center. The cobalt atom attaches to a methyl group, a deoxyadenosyl group, an hydroxyl group or a cyano group, to yield the four cobalamin forms mentioned above.
