NAD+ is not a peptide. It is a naturally occurring dinucleotide coenzyme present in virtually every living cell and plays a central role in cellular metabolism, redox reactions, mitochondrial biology, and energy production. Researchers continue to investigate NAD+ in laboratory models involving mitochondrial function, cellular respiration, oxidative phosphorylation, DNA repair pathways, sirtuin biology, PARP activity, CD38 metabolism, and molecular signaling.
Our research-grade NAD+ is supplied exclusively for laboratory and analytical research purposes.
