NAD+

NAD⁺ is a naturally occurring coenzyme found in all living cells, central to cellular energy metabolism and redox biochemistry. Supplied as a lyophilized powder in a sealed laboratory-grade glass vial. Intended for in-vitro and laboratory research applications only.

Research Context
NAD⁺ acts as a hydride-transferring coenzyme in cellular redox reactions, cycling between its oxidized (NAD⁺) and reduced (NADH) forms within mitochondrial and cytoplasmic metabolic pathways including glycolysis, the citric acid cycle, and oxidative phosphorylation. It is also a substrate for sirtuin deacylases (SIRT1–7), poly(ADP-ribose) polymerases (PARPs), and CD38 signalling, making it a subject of in-vitro and animal-model studies into DNA-repair, mitochondrial-biogenesis, and inflammatory signalling pathways. Its documented decline with age makes it a research subject in the study of longevity biology, metabolic pathways, and neuronal signalling.
