NMN is a natural substance found in the body and is abundant in some fruits and vegetables. In the human body, NMN is the precursor of NAD+, and its function is reflected by NAD+. NAD + is coenzymeI, named nicotinamide adenine dinucleotide, It exists in thousands of substance's cell reaction. NAD+ is an important coenzyme of the tricarboxylic acid cycle, which promotes the metabolism of sugar, fat and amino acids and participates in the synthesis of energy. NAD+ is the only substrate of coenzyme I consuming enzyme (the only substrate of DNA repair enzyme PARP, the only substrate of longevity protein Sirtuins, and the only substrate of cyclic ADP ribosomal synthetase cd38/157). NMN is produced under the catalysis of Nampt, and then NMN generates NAD+ under the catalysis of nicotinamide mononucleotideadenosine transferase (Nmnat). NMN exerts its physiological functions in the human body by conversion to NAD+, such as activation of the NAD+ substrate-dependent enzyme Sirt1 (histone deacetylase, also known as sirtuin), regulation of cell survival and death, maintenance of redox status, and the like. Sirt1 is a NAD+-dependent enzyme that complements NMN to accelerate the turnover of remedial biosynthesis of NAD+, thereby activating the Sirt1 response. Sirt1 can induce DNA silencing, helping to fight aging and prolong life.
