In its oxidised form it participates in the electron-transfer reactions underlying glycolysis, oxidative phosphorylation and mitochondrial energy production. It is supplied pre-mixed in a sealed 3 ml vial, strictly for in-vitro laboratory research use only."},{"question":"Is NAD+ a peptide?","answer":"No. NAD+ is a pyridine-nucleotide coenzyme — nicotinamide mononucleotide joined to adenosine monophosphate through a pyrophosphate bridge — not a chain of amino acids. It is often searched for as an \"NAD peptide\" or \"NAD+ peptide\" because the same suppliers and laboratories work with both, but it is a different class of molecule and it behaves differently in solution, which is why its handling notes differ from those for a peptide."},{"question":"What is the difference between NAD+, NMN and NR?","answer":"They are three points on one pathway. NR (nicotinamide riboside) is phosphorylated by NRK1/2 kinases to NMN (nicotinamide mononucleotide), and NMN is converted by NMNAT enzymes to NAD+, the coenzyme itself. Cell-free and enzymology work uses NAD+ directly as the substrate or cofactor; cell-based work on NAD+ availability often supplies a precursor instead, because how extracellular NAD+ crosses an intact cell membrane is still an open research question. This kit supplies the coenzyme."},{"question":"What is NAD+ studied for in research?","answer":"In biochemical and cellular research systems, NAD+ has been investigated for its role in redox balance and as a substrate for NAD+-dependent enzymes. Reported laboratory work covers its involvement in signalling pathways including sirtuins, poly(ADP-ribose) polymerases (PARPs) and cyclic ADP-ribose-generating enzymes linked to DNA repair, chromatin regulation and calcium signalling. These are preclinical, cell-based observations, and experimental outcomes depend on intracellular NAD+/NADH ratios, compartmentalisation and the metabolic state of the model system."},{"question":"Is NAD+ legal to buy in the UK?","answer":"The NAD+ Kit is legal to buy and possess in the UK for laboratory research purposes. It is not a licensed medicine and cannot be sold or supplied for human or veterinary consumption. Every order ships labelled for in-vitro research use only."},{"question":"What purity is your NAD+, and is it lab-tested?","answer":"The NAD+ Kit is verified to 99%+ purity by HPLC analysis. The figure printed on each batch's Certificate of Analysis is the actual lab-recorded value for that batch, not a marketing claim.
