    Nicotinamide adenine dinucleotide (abbreviated as NAD), also known as pyridine diphosphate nucleotide (abbreviated as DPN), or codehydrogenase I or coenzyme I.  Nicotinamide adenine dinucleotide is involved in various physiological activities such as cellular material metabolism, energy synthesis, and cellular DNA repair, and plays an important role in the immune capacity of the body.  Under healthy conditions, the concentration of nicotinamide adenine dinucleotide in the human body remains stable, maintaining the normal functions of various cells.  The concentration of nicotinamide adenine dinucleotide in the body determines the process and degree of cellular senescence. A decrease in concentration will accelerate the process of cellular senescence.
