What it is
Vitamin B12 (cobalamin) is a cobalt-containing vitamin, not a peptide. It is a cofactor for the enzymes methionine synthase and methylmalonyl-CoA mutase.
Identity
| Type | Vitamin (cobalamin), supplied in solution |
|---|---|
| Form | Stated on the certificate of analysis (cyanocobalamin or methylcobalamin) |
What the published research covers
Cobalamin biochemistry is long established: it is required for methyl transfer in the folate cycle and for the breakdown of odd-chain fatty acids and some amino acids.
Regulatory status
Cyanocobalamin exists as an FDA-approved prescription injection. This material is not that product and is supplied for laboratory research only.
Testing and documentation
Not a peptide, so peptide HPLC purity does not apply. The certificate of analysis states the form and the concentration.
