What is the chemical formula of vitamin B12?

Vitamin B-12, also known as cyanocobalamin, is a water-soluble vitamin that is part of the B-12 family. B Vitamins help adrenal support function, promote calm and maintain a healthy nervous system, and are necessary for vital metabolic processes. It contains a biochemically rare element called cobalt, (chemical symbol Co) positioned in the center of a corrin ring.

It is one of eight B vitamins, and it is the largest and most structurally complex vitamins. The structure of B-12 is based on a corrin ring, which is similar to the porphyrin ring. The central metal ion is cobalt. The reactive center is a cyano group (-CN), a hydroxyl group (-OHS, to a methyl group (CH third), a hydroxyl group S’ deoxyadenosyl group (here is the C5’ atom of the deoxyadenosyl group (here is the C5’ atom of deoxyribose forms of the covalent bond with cobalt.) The covalent C-Co bond with the first examples of carbon-metal bonds to be discovered in biology. Vitamin B-12 is a generic descriptor name referring to a collection of cobalt and corrin ring molecules.
