What NAD+ is
NAD+ (nicotinamide adenine dinucleotide, oxidised form) is a coenzyme, not a peptide. It is included here because it is commonly supplied alongside research peptides in a laboratory-supply context. NAD+ is central to cellular redox biology and is a substrate for sirtuins, PARPs and CD38.
Molecular information
- Compound class: Dinucleotide coenzyme
- Molecular formula: C₂₁H₂₇N₇O₁₄P₂
- Approximate molecular mass: ~663 g/mol
- Physical form: Typically supplied as a white powder
Areas of published research
Published research on NAD+ spans redox biology, cellular energetics, sirtuin activity, DNA-damage response and ageing research. Because NAD+ is a small molecule rather than a peptide, its analytical characterisation uses standard organic-chemistry techniques — HPLC with UV detection at 260 nm (adenine absorbance), LC-MS with electrospray, and enzymatic assays for functional integrity — rather than peptide-specific methods.
Analytical considerations
Standard research-peptide analytical checks apply: identity confirmation by mass spectrometry (see LC-MS peptide testing explained), purity assessment by reversed-phase HPLC at 214 nm (see what is HPLC peptide testing), and batch-specific documentation (see how to read a peptide COA). Refer to the Peptovia Research Certificate of Analysis page for live examples of the analytical format used for batches supplied.
Further reading
Peer-reviewed literature on NAD+ is accessible via PubMed and specialist journals. Readers are encouraged to evaluate primary sources directly rather than relying on secondary summaries.
