Application

NAD has been used in in vitro glycogen synthase kinase 3 (GSK3) deacetylation assay. It has also been used as a component in assay mixfor the determination of kinetic characteristics using an enzyme-linked kinetic assay.

NAD (nicotinamide adenine dinucleotide), Grade I has been used in the kinetic studies of human class IV alcohol dehydrogenase.

Biochem/physiol Actions

The NAD (nicotinamide adenine dinucleotide)/NADH ratio regulates the intracellular redox potential, thereby influencing metabolic reactions in vivo. It works as an electron acceptor.

NAD is also involved in microbial catabolism. β-NAD acts as a substrate for various enzymes in several cellular processes.

Electron acceptor

General description

Nicotinamide adenine dinucleotide (NAD) is a ubiquitously found electron carrier and a cofactor. NAD⁺ contains an adenylic acid and a nicotinamide-5′-ribonucleotide group linked together by a pyrophosphate moiety. In NAD⁺ complexes, the enzyme-cofactor interactions are highly conserved.
