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 activ
