Nicotinamide adenine dinucleotide reduced form (NADH) disodium salt 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 NADH to a substrate molecule to form the oxidized product NAD. The reaction is easily reversible when NAD+ oxidizes another molecule and is re-reduced to NADH. 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.
