Product Detail

Here is an English product overvied for B12 :

Composition:

Vitamin B12 (cyanocobalamin) is a water-soluble organometallic compound featuring a central cobalt ion coordinated within a corrin ring structure, with the molecular formula C₆₃H₈₈CoN₁₄O₁₄P. It is structurally characterized by a nucleotide loop containing a dimethylbenzimidazole base linked to the corrin macrocycle via a phosphate ester bond. For laboratory purposes, it is supplied as a dark red crystalline powder or in sterile aqueous solution, maintained under light-protected conditions to preserve stability, and is free from thiol-containing reducing agents or other reactive additives.

Mechanism of Action:

Following internalization via receptor-mediated endocytosis, the compound is converted intracellularly into two active coenzyme forms: methylcobalamin and 5-deoxyadenosylcobalamin. Methylcobalamin functions as an essential cofactor for methionine synthase, catalyzing the transfer of a methyl group from 5-methyltetrahydrofolate to homocysteine, thereby regenerating methionine and tetrahydrofolate for nucleotide biosynthesis. Concurrently, 5-deoxyadenosylcobalamin acts as a coenzyme for methylmalonyl-CoA mutase in the mitochondrial matrix, facilitating the isomerization of methylmalonyl-CoA to succinyl-CoA, which integrates lipid and amino acid catabolism into the citric acid cycle.

Research Advantages:

As a stable, well-defined corrinoid, Vitamin B12 serves as an ideal reference standard for studying cobalt-dependent enzymatic catalysis and one-carbon metabolism without the complications of redox-active thiol groups or unstable intermediates. Its distinct absorption kinetics and cellular transport mechanisms provide clear models for investigating receptor-ligand interactions and endosomal trafficking. The compound’s dual role in nucleic acid synthesis and energy metabolism allows researchers to examine interconnected biochemical pathways within a single, physiologically relevant system.

Intended Research Population:

This compound is designated for in vitro and cellular investigations involving folate-cycle interactions, homocysteine remodeling, and mitochondrial metabolic flux analysis. It is utilized in research models of megaloblastic hematopoiesis, demyelinating neurological pathways, and age-related declines in cellular methylation capacity. It remains a laboratory-grade investigational reagent and is not approved for therapeutic, diagnostic, or clinical application in humans or animals outside controlled experimental protocols.
