Nicotinamide Adenine Dinucleotide (NAD)

Overview:

Nicotinamide adenine dinucleotide (NAD) is a coenzyme necessary for the catalytic reaction of certain metabolic enzymes found in all living cells (1). It consists of two nucleosides joined by a pyrophosphate (2). Enzymes catalyze the reversable transfer of a hydride ion (H-) from the substrate molecule to NAD to form the reduced product NADH. The reaction is easily reversible, when NADH reduces another molecule and is re-oxidized to NAD+. Thus, the coenzyme can continuously cycle between the NAD+ and NADH forms without being consumed (3). Laboratory applications of this enzyme include biocatalytic synthesis reactions, and kinetic studies. It can also be used as a cofactor in various diagnostic tests.
