Coenzyme

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell and central to energy metabolism and cellular repair signaling.

What it is

NAD+ is studied as a substrate for sirtuins and PARP enzymes and as a carrier in cellular energy (redox) reactions. Because NAD+ levels are studied in the context of aging, it is a major reference molecule in longevity and mitochondrial research.

How it’s studied

Research spans cellular energy metabolism, DNA-repair signaling, sirtuin biology, and aging models.

Research focus areas

  • Cellular energy (redox) metabolism
  • Sirtuin and PARP enzyme substrate biology
  • DNA-repair signaling
  • Longevity and mitochondrial research

Handling & documentation

NAD+ is a coenzyme typically supplied as a powder for in-vitro laboratory research. Confirm identity and purity against a lot-specific Certificate of Analysis (COA) from an independent lab, and store per the supplier’s guidance.
