Dehydrogenase

A dehydrogenase is an enzyme that oxidizes a substrate by a reduction reaction that transfers one or more hydrides (H⁻) to an electron acceptor, usually Nicotinamide adenine dinucleotide NAD⁺/NADP.

Chemical reaction

$NADH \rightleftharpoons NAD$

Rate equation

Reversible mass action rate law is used

$K_{1}[NADH] - K_{2}[NAD]$
