Description
NAD+ is a dinucleotide composed of nicotinamide mononucleotide and adenosine monophosphate joined through a pyrophosphate linkage. It is not a peptide. NAD exists in two interconvertible forms, the oxidized NAD+ and the reduced NADH, which differ by a hydride at the nicotinamide ring.
In biochemistry, NAD+/NADH functions as a redox cofactor in oxidoreductase-catalyzed reactions, and NAD+ additionally serves as a substrate for ADP-ribosyl transfer and sirtuin-catalyzed deacylation reactions. This material is supplied as a characterized reference compound for non-clinical laboratory work, such as enzyme assays requiring an NAD+/NADH couple, spectrophotometric and fluorometric cofactor quantitation at 340 nm, dehydrogenase kinetics, sirtuin and PARP activity assays, and analytical method development.
