NAD+ (nicotinamide adenine dinucleotide, oxidised form) is a dinucleotide coenzyme made of two nucleotides, one carrying nicotinamide and one carrying adenine, joined through a pyrophosphate bridge. It is present in every living cell.
Research interest centres on its two roles in cell biochemistry: as an electron carrier in redox reactions of glycolysis, the citric acid cycle and the mitochondrial electron transport chain, and as a consumed substrate for sirtuin deacetylases and PARP enzymes. Laboratory studies examine NAD+/NADH ratios, sirtuin pathway activity and mitochondrial function in cell and enzyme assays.
Each vial contains 500 or 1000 mg of NAD+ (select a size above) as a lyophilized powder. Reconstitute with bacteriostatic water (sold separately) before laboratory use. The COA & Testing tab lists the tested batch, with links to verify it on COA Coalition and with the laboratory.
