Vitamin B12, vitamin B12 or vitamin B-12, also called cobalamin, is a water-soluble vitamin with a key role in the normal functioning of the brain and nervous system, and for the formation of blood. It is one of the eight B vitamins. It is normally involved in the metabolism of every cell of the human body, especially affecting DNA synthesis and regulation, but also fatty acid synthesis and energy production. Neither fungi, plants, nor animals are capable of producing vitamin B12. Only bacteria and archaea have the enzymes required for its synthesis, although many foods are a natural source of B12 because of bacterial symbiosis. The vitamin is the largest and most structurally complicated vitamin and can be produced industrially only through bacterial fermentation-synthesis.
List of Vitamin B complex group
Vitamin B1 thiamine A coenzyme in the catabolism of sugars and amino acids.
Vitamin B2 riboflavin A precursor of cofactors called FAD and FMN, which are needed for flavoprotein enzyme reactions, including activation of other vitamins
Vitamin B3 niacin (nicotinic acid), nicotinamide riboside A precursor of coenzymes called NAD and NADP, which are needed in many metabolic processes.
Vitamin B5 pantothenic acid A precursor of coenzyme A and therefore needed to metabolize many molecules.
Vitamin B6 pyridoxine, pyridoxal, pyridoxamine A coenzyme in many enzymatic reactions in metabolism.
Vitamin B7 biotin A coenzyme for carboxylase enzymes, needed for synthesis of fatty acids and in gluconeogenesis.
Vitamin B9 folate A precursor needed to make, repair, and methylate DNA; a cofactor in various reactions; especially important in aiding rapid cell division and growth, such as in infancy and pregnancy. Synthetic folate is known as folic acid.
Vitamin B12 various cobalamins; commonly cyanocobalamin or methylcobalamin in vitamin supplements A coenzyme involved in the metabolism of every cell of the human body, especially affecting DNA synthesis and regulation, but also fatty acid metabolism and amino acid metabolism.
