Beschreibung
Coenzyme B12 (adenosylcobalamin; AdoCbl; 5'-Deoxyadenosylcobalamin) is a form of vitamin B12. It belongs to the corrinoid group of compounds containing a corrin macrocycle and are produced only by certain bacteria and archaea. It is a cofactor for various enzymes, including mutases, eliminases, aminomutases, and reductases. These enzymes catalyze reactions that generate free radicals through the release of the adenosyl group, allowing usually unreactive molecules to become reactive. Genetic mutations in enzymes synthesizing Coenzyme B12 lead to Coenzyme B12 deficiency and methylmalonic aciduria.

Definition
ChEBI: A member of the class of cobalamins that is vitamin B12 in which the cyano group is replaced by a 5'-deoxyadenos-5'-yl moiety. It is one of the two metabolically active form of vitamin B12.
Allgemeine Beschreibung
Vitamin B
12 cobalamin refers to a group of chemically-related cobalt containing molecules. The physiologically active forms of vitamin B
12 include methylcobalamin and adenosylcobalamin, whereas hydroxocobalamin (vitamin B
12a, OHCbl) and cyanocobalamin (CNCbl) are storage and delivery forms.
Landwirtschaftliche Anwendung
Cobamide enzyme is the cobalt complex formed between the cobalt-porphyrin ring structure and the nucleotide in vitamin B
12 co-enzyme.
