Vitamin B 12 is a coordination complex of cobalt, which occupies the center of a corrin ligand and is further bound to a benzimidazole ligand and adenosyl group. [18] Several related species are known and these behave similarly, in particular, all function as vitamins. This collection of compounds is sometimes referred to as "cobalamins".
Adenosylcobalamin (AdoCbl), also known as coenzyme B 12, cobamamide, and dibencozide, is one of the biologically active forms of vitamin B 12. [ 1 ] Schematic diagram of the propionate metabolic pathway.
Cobalamin biosynthesis is the process by which bacteria and archea make cobalamin, vitamin B 12. Many steps are involved in converting aminolevulinic acid via uroporphyrinogen III and adenosylcobyric acid to the final forms in which it is used by enzymes in both the producing organisms and other species, including humans who acquire it through ...
Vitamin B12 is good for your brain and may help improve memory. But it also helps your red blood cells and nerves function, as well as assisting in the production of DNA, says Brian St. Pierre, ...
Vitamin Name Structure Molecular function Vitamin B 1: Thiamine: Thiamine plays a central role in the release of energy from carbohydrates. It is involved in RNA and DNA production, as well as nerve function. Its active form is a coenzyme called thiamine pyrophosphate (TPP), which takes part in the conversion of pyruvate to acetyl coenzyme A in ...
Vitamin B12 does also accumulate in a few plant-based sources, including some mushrooms, seaweed, and nutritional yeast, but not enough to fortify vegans, who, in particular, should consider being ...
In molecular biology, the vitamin B12-binding domain is a protein domain which binds to cobalamin (vitamin B12). It can bind two different forms of the cobalamin cofactor, with cobalt bonded either to a methyl group (methylcobalamin) or to 5'-deoxyadenosine (adenosylcobalamin).
Vitamin B12 also helps your central nervous system function properly, while iron helps support muscle metabolism. Both chicken and turkey are versatile and can serve as the star of a weeknight meal .
