Common Namebeta-nicotinamide D-ribonucleotide
DescriptionNicotinamide ribotide, also known as NMN, belongs to the class of organic compounds known as nicotinamide nucleotides. These are pyridine nucleotides, in which the pyridine base is nicotinamide or a derivative thereof. Nicotinamide ribotide (NMN) is an important intermediate metabolite in the nicotinate and nicotinamide metabolism pathway. Nicotinamide ribotide is an extremely weak basic (essentially neutral) compound (based on its pKa). Nicotinamide ribotide exists in all eukaryotes, ranging from yeast to humans. Instead of the deamidation to nicotinic acid, nicotinamide is directly converted to Nicotinamide ribotide by nicotinamide phosphoribosyltransferase (NAMPT, EC2.4.2.12). Within humans, nicotinamide ribotide participates in a number of enzymatic reactions. In particular, nicotinamide ribotide can be biosynthesized from nicotinamide riboside through its interaction with the enzyme cytosolic purine 5'-nucleotidase. In addition, nicotinamide ribotide can be biosynthesized from niacinamide and phosphoribosyl pyrophosphate through its interaction with the enzyme nicotinamide phosphoribosyltransferase. The enzyme Nicotinamide ribotide adenylyltransferase (NMNAT, 12), a member of the nucleotidyltransferase alpha/beta-phosphodiesterase superfamily, catalyzes the reaction Nicotinamide ribotide + ATP = Nicotinamide adenine dinucleotide (NAD) + PPi, representing the final step in the biosynthesis of NAD, a molecule playing a fundamental role as a cofactor in cellular redox reactions. In humans, nicotinamide ribotide is involved in nicotinate and nicotinamide metabolism. Thus Nicotinamide ribotide is an important metabolite for the maintenance of normal NAD biosynthesis, and circulating Nicotinamide ribotide levels may play an important role in regulating cell function in physiological and pathophysiological conditions. Mammals predominantly use nicotinamide rather than nicotinic acid as a precursor for NAD biosynthesis.
