Vedi i risultati di laboratorio →NAD+ (Nicotinamide Adenine Dinucleotide) is a crucial coenzyme involved in oxidation-reduction (redox) reactions, serving as an electron carrier in cellular bioenergetics. It plays a fundamental role in metabolic pathways, including glycolysis, the citric acid cycle, and oxidative phosphorylation.
This pyridine nucleotide exists in both oxidized (NAD⁺) and reduced (NADH) states, enabling its function in enzymatic catalysis and cofactor-dependent biochemical reactions. NAD+ is metabolized through enzymatic cleavage, salvage pathways, and poly(ADP-ribose) polymerase (PARP) activity, with primary clearance via renal and hepatic pathways.
NAD+ 100 mg should be reconstituted with bacteriostatic water (BAC).

How does NAD+ differ from NAD+ precursor compounds in biochemical research?
NAD+ is the oxidized dinucleotide cofactor itself, whereas compounds such as nicotinamide mononucleotide (NMN) and nicotinamide riboside (NR) participate in NAD+ biosynthetic pathways. This distinction makes NAD+ a useful research tool for investigating NAD+-dependent enzymatic reactions, cofactor utilization mechanisms, redox system dynamics, and the biochemical relationships between NAD+ and precursor-associated pathways.
Which enzyme families utilize NAD+ as a substrate?
NAD+ serves as an obligate substrate for three major enzyme families: poly(ADP-ribose) polymerases (PARPs), sirtuins (SIRT1–7), and CD38/CD157 ADP-ribosyl cyclases. These enzymes utilize NAD+ in processes involving protein modification, enzymatic regulation, signal transduction, and cofactor-dependent biochemical activity.
Their dependence on NAD+ has made them important targets for investigations of enzyme-cofactor interactions and NAD+-associated regulatory mechanisms.
Why is NAD+ widely used in biochemical research?
NAD+ occupies a central role in both redox chemistry and enzyme-mediated regulatory systems. In addition to functioning as a reversible electron carrier, it participates directly in the catalytic activity of multiple NAD+-dependent enzyme families.
These characteristics have established NAD+ as a valuable research tool for investigating redox biology, enzyme kinetics, cofactor-dependent catalysis, sirtuin pharmacology, PARP biochemistry, CD38-associated pathways, and the molecular mechanisms governing NAD+-dependent biochemical processes.
