High Purity CAS 53-84-9

β-Nicotinamide Adenine Dinucleotide CAS 53-84-9 is a fundamental biological coenzyme found in all living cells. It is a dinucleotide consisting of two nucleotides joined through their phosphate groups: one nucleotide contains an adenine base (adenosine monophosphate, AMP), and the other contains a nicotinamide base (nicotinamide mononucleotide, NMN). The "β" denotes the stereospecific configuration of the glycosidic bond in the nicotinamide riboside moiety, which is essential for biological activity. NAD+ exists in two interconvertible redox states: the oxidized form (NAD+) and the reduced form (NADH).β-Nicotinamide Adenine Dinucleotide  is the universal and indispensable redox coenzyme central to cellular metabolism and signaling. It is not merely a supplement but the active, endpoint molecule​ itself, serving as the direct co-substrate for hundreds of enzymes that govern energy production, genomic repair, and epigenetic regulation.
