NAD Nicotinamide adenine dinucleotide; a coenzyme for dehydrogenases; reduced form is NADH. Formerly called DPN (diphosphopyridine nucleotide), previously Coenzyme I
(Nicotinamide adenine dinucleotide) The oxisided form of the coenzyme of an enzyme involved in respiration. NADH2 is the reduced form of the coenzyme. NAD was formerly called DPN (diphosphorpyridine nucleotide).
A compound found in all living cells, existing in two interconvertible forms: the oxidizing agent NAD+ and the reducing agent NADH.
Coenzyme that participates in an oxidation reaction by accepting a hydride ion (H-) from a donor molecule. The NADH formed is an important carrier of electrons for oxidative phosphorylation.
a coenzyme present in most living cells and derived from the B vitamin nicotinic acid; serves as a reductant in various metabolic processes
A coenzyme that acts as an electron acceptor; particularly important in respiration.
nicotinamide adenine dinucleotide. a coenzyme that functions during respiration to produce ATP.
Nicotinamide Adenine Dinucleotide, a coenzyme involved in redox reactions.
Nicotinamide adenine dinucleotide (NAD) is a molecule that binds with hydrogen atoms during alcohol metabolism and becomes reduced NAD, or NADH. NAD and NADH move hydrogen atoms back and forth between various oxidationâ€“reduction reactions, helping to maintain balance between oxidation and reduction in the cell.

nicotinamide adenine dinucleotide. An energy carrier molecule, used directly by enzymes or to shuttle energy to the electron transport system. Synthesized from the vitamin niacin (nicotinic acid).
Nicotinamide adenine dinucleotide. An important coenzyme, functioning as a hydrogen carrier in a wide range of redox reactions; the H is carried on the nicotinamide residue. The oxidized form of the coenzyme is written NAD+, the reduced form as NADH (or NADH+H+).
A widely used coenzyme that participates in oxidation reactions by accepting two electrons from a donor molecule and one H+ from the solution. The reduced form, NADH, transfers electrons to carriers that function in oxidative phosphorylation. ( Figure 16-4)
