NMN

Nicotinamide mononucleotide(NMN)

I. What is NMN

NMN is the abbreviation of Nicotinamide mononucleotide, which is inherent in the human body. In the human body, NMN is a precursor of NAD+, NAD+also known as coenzyme I, is a full name of nicotinamide adenine dinucleotide, also known as nicotinic acid diphosphate, which participates in thousands of reactions in each cell. NAD+ is an important coenzyme of the Krebs cycle, promoting the metabolism of sugars, fats and amino acids, and participating in the synthesis of energy; NAD+ is the only substrate for coenzyme I depleting enzymes (the only substrate for the DNA repair enzyme PARP, the only long-lived protein Sirtuins). As a precursor of NAD+, NMN functions through NAD+, and the metabolism of NNM and NAD+ is linked.
