Adenosylcobalamin (Vitamin B12, coenzyme B12) — living evidence map

The Atlas page holds the claims; this is how its evidence evolved.

Summary

Adenosylcobalamin is one of the two coenzyme forms of vitamin B12 (cobalamin), one of the most structurally complex small molecules made in nature; its full biosynthesis from uroporphyrinogen III has been worked out. · pmid:12195810

Mechanism

Adenosylcobalamin is the coenzyme of the mitochondrial enzyme methylmalonyl-CoA mutase; in a child with the cblB form of methylmalonic acidaemia, intramuscular adenosylcobalamin raised serum cobalamin greatly but lowered methylmalonic acid excretion only briefly. · pmid:6434828

Identity

PubChem CID 6474320: Coenzyme B12, C72H100CoN18O17P, 1579.6 g/mol. · pubchem:6474320

CAS registry number 13870-90-1. · pubchem:6474320

Structure

No structure representation on record. PepJunkie draws only what an authoritative record supplies; for a peptide that is the residue sequence, and none has been curated for Adenosylcobalamin (Vitamin B12, coenzyme B12) yet.


Dose evidence, rung by rung

No established safe human dose. Nothing on file establishes one. That is a statement about the evidence PepJunkie holds, not a promise about the molecule.
