Description

Description générale

Nicotinamide adenine dinucleotide (NAD) is a ubiquitously[1] found electron carrier[2] 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.[1]

Application

NAD (nicotinamide adenine dinucleotide), Grade I has been used in the kinetic studies of human class IV alcohol dehydrogenase.[3]

NAD has been used in in vitro glycogen synthase kinase 3 (GSK3) deacetylation assay.[4] It has also been used as a component in assay mix for the determination of kinetic characteristics using an enzyme-linked kinetic assay.[5]

Actions biochimiques/physiologiques

Accepteur d'électrons

NAD is also involved in microbial catabolism.[6] β-NAD acts as a substrate for various enzymes in several cellular processes.[7]

The NAD (nicotinamide adenine dinucleotide)/NADH ratio regulates the intracellular redox potential, thereby influencing metabolic reactions in vivo.[8] It works as an electron acceptor.[9]
