Vitamin B12, also known as cobalamin, is a water-soluble vitamin involved in metabolism. [2] It is one of eight B vitamins. It is required by animals, which use it as a cofactor in DNA synthesis, and in both fatty acid and amino acid metabolism. [3]
Vitamin B 12 total synthesis. The total synthesis of the complex biomolecule vitamin B 12 was accomplished in two different approaches by the collaborating research groups of Robert Burns Woodward at Harvard [1] [2] [3] [4] [5] and Albert Eschenmoser at ETH [6] [7] [8] [9] [10] [11] [12] in 1972.
As a supplement it is used to treat vitamin B12 deficiency including pernicious anemia. Other uses include treatment for cyanide poisoning, Leber's optic atrophy, and toxic amblyopia. It is given by injection into a muscle or vein. Side effects are generally few.
Adenosylcobalamin (AdoCbl), also known as coenzyme B12, cobamamide, and dibencozide, is, along with methylcobalamin (MeCbl), one of the biologically active forms of vitamin B 12. [1] Adenosylcobalamin participates as a cofactor in radical-mediated 1,2-carbon skeleton rearrangements.
Serum vitamin B12 is a medical laboratory test that measure vitamin B 12 only in the blood binding to both transcobalamins. [1] . Most of the time, 80–94% of vitamin B 12 in the blood binds to haptocorrin, while only 6–20% is binds to transcobalamin ll. [2] Only transcobalamin ll is "active" and can be used by the body. [1] .
Cyanocobalamin is a form of vitamin B. 12 used to treat and prevent vitamin B. 12 deficiency except in the presence of cyanide toxicity. [7] [8] [2] The deficiency may occur in pernicious anemia, following surgical removal of the stomach, with fish tapeworm, or due to bowel cancer.
The dark red crystals dissolve in water giving cherry-colored solutions. 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 ...
