Nicotinamide adenine dinucleotide — the coenzyme central to cellular electron-transfer, sirtuin signalling, and redox biology.

Chemistry quick-facts

CAS
53-84-9
Formula
C21H27N7O14P2
MW
663.43 Da
Status
NAD⁺ is a naturally occurring dinucleotide coenzyme, not a peptide. Precursor molecules (NR, NMN) are supplement-regulated in most jurisdictions. Research-grade NAD⁺ is supplied by Omega Grade for laboratory work only.
Purity (HPLC)
≥ 99.0%

Mechanism of action

Substrate for sirtuins, PARPs, CD38; central redox cofactor (NAD⁺/NADH) in electron-transport chain.

Research context

NAD⁺ is an essential dinucleotide coenzyme found in all living cells, central to cellular energy metabolism, redox chemistry, sirtuin-mediated signalling, and DNA-repair enzymes (PARPs).

NAD⁺ research has expanded rapidly with the recognition of its role in aging, metabolic function, and cellular senescence. NAD⁺ precursors (NR, NMN) are widely studied as oral bioavailable alternatives.

FAQ

Why isn't this a peptide?+

NAD⁺ is a dinucleotide coenzyme, not a peptide. It is included in the Omega Grade catalogue because it is commonly used alongside mitochondrial and metabolic peptides in research protocols.
