NAD+: Research Background
NAD+ is not a peptide but a dinucleotide coenzyme: two nucleotides, one containing nicotinamide and one adenine, joined by a pyrophosphate bridge. Cells make it through a de novo pathway from tryptophan, the Preiss-Handler pathway from nicotinic acid, and the salvage pathway in which NAMPT converts nicotinamide to NMN.
Beyond its role as an electron carrier (the NAD+/NADH pair), NAD+ is consumed as a substrate by sirtuins, PARP enzymes and CD38, which links NAD+ availability to DNA repair, protein deacetylation and signalling research.
Published reviews describe changes in NAD+ levels across ageing models, making it a common reference compound in metabolism and mitochondrial studies.
What the NAD+ COA Confirms
OxygenLab products are tested by independent third-party laboratories. HPLC reports purity as the main peak’s share of total peak area, and mass spectrometry confirms identity against the expected molecular weight of 663.4 g/mol. Published certificates are on our COA page, and others are available on request; match the lot number on your vial to the report before use in an experiment.

More Questions About NAD+
Is NAD+ a peptide?
No. It is a dinucleotide coenzyme, supplied alongside research peptides because it is used in the same mitochondrial and metabolic research areas.
Which enzymes consume NAD+?
Sirtuins, PARPs and CD38 use NAD+ as a substrate.
Storage and Handling
- Store lyophilized powder at -20°C for long-term storage, protected from light and moisture.
- Short-term storage at 2–8°C is acceptable for unopened vials.
- Allow the vial to reach room temperature before opening to limit moisture uptake.
- Record batch and lot numbers for every preparation.
