Vitamin B12, (Cobalamin)

The structure of vitamin B12 is the most complicated complex of all vitamins. Its molecule has similar a porphyrin cycle to that in haem and chlorophylls dyes, but with cobalt as a central atom. Vitamin B12 occurs in several major forms: as hydroxy-, cyano- and methylcobalamin. Vitamin B12 serves as a cofactor, which is involved in several enzymatic reactions. This vitamin is industrially produced through special fermentation using bacteria.

Vitamin B12 contributes to normal energy-yielding metabolism, normal functioning of the nervous system, normal homocysteine metabolism, normal psychological function and normal red blood cell formation. Furthermore, it contributes to the normal function of the immune system and reduces tiredness and fatigue. Vitamin B12 also has a role in the process of cell division.
