NMN, or β-nicotinamide mononucleotide, is a nicotinic acid derivative that contains nicotinamide, ribose, and phosphate groups.
NMN has a molecular weight of 334 and has two diastereomers: α and β. Only β is biologically active.
NMN is a substance that exists naturally in the human body and is also naturally present in some fruits, vegetables and poultry.
The function of NMN is manifested through NAD+ (coenzyme I, nicotinamide adenine dinucleotide).
NMN is an effective precursor of NAD+, and forms NAD+ under the support of the energy substance ATP.
