Cofactor research materials

NAD+

NAD+ research vials are common staples. Look for content assays that show measured mass near labeled strength.

NAD+ is a dinucleotide cofactor, not a peptide, so it has no amino acid sequence.

Verified 2026-11-09 against PubChem CID 5892. Values we could not verify are left out.

How NAD+ is thought to work

Evidence level: Established biochemistry (review). See every diagram in the mechanism map library.

NAD+ mechanism diagramRedox cofactor and substrate for NAD+-consuming enzymes. Targets: Redox cofactor, Sirtuins, PARPs. Recycling after consumption (salvage pathway): Nicotinamide → NAMPT → NMN → NAD+. Downstream processes: Energy metabolism, Protein deacylation, DNA-damage signaling.NAD+ mechanism mapRedox cofactor and substrate for NAD+-consuming enzymesNAD+dinucleotide cofactorRedox cofactorNAD+ ⇄ NADH [1]SirtuinsSIRT1–7 substrate [1]PARPsPARP1 and others [1]Energy metabolismglycolysis, TCA, OXPHOS[1]Protein deacylationsirtuins [1]DNA-damage signalingPARPs [1]Nicotinamide[1]NAMPT[1]NMN → NAD+[1]Evidence: Established biochemistry (review).

Research context

UPV highlights vendors that publish lab-hosted certificates for NAD+ lots rather than undated marketing PDFs.

Buyer notes

  • Content assay (measured mg) is especially useful for NAD+ lots
  • Check storage guidance on the vendor FAQ for lab handling
