Nicotinamide adenine dinucleotide (NAD or NAD+) was once called pyridine diphosphate nucleotide (DPN) or coenzyme I or oxidative coenzyme I. It is a coenzyme that transports electrons (more precisely hydrogen ions), which occurs in many cellular metabolic reactions, participate in cell metabolism, energy synthesis, cell DNA repair and so on in the process of physiological activation.
