NAD(+)
CofactorMech:nad · CHEBI:15846
NAD(+) is represented by the precise ChEBI entity CHEBI:15846. Cofactor roles are chemical-context annotations; ingredient links describe chemical supply and do not establish uptake, bioavailability or a requirement for every organism.

Scoped relationships
Provisional links retain upstream ingredient identifiers. Verified links describe the cited source context, not universal organism requirements. Conjugate forms and precursor supply are distinct relationships.
Supplied by · CHEBI:15846
PROVISIONAL · mediaingredientmech
The current MIM ontology mapping exactly matches the candidate cofactor chemical identifier. This establishes a compound supply link, not organism-specific uptake or requirement.

Research gaps
- proteintraitsmech: The curated PTM link covers a cofactor-requirement concept only. A separately sourced, named enzyme exemplar requiring this exact chemical has not been curated in this seed record.
