A dehydrogenase is an enzyme belonging to the group of oxidoreductases that oxidizes a substrate by reducing an electron acceptor, usually NAD⁺/NADP⁺ or a flavin coenzyme such as FAD or FMN.

Is dehydrogenase oxidation or reduction?

Dehydrogenases are intracellular enzymes that catalyze oxidation–reduction reactions required for the respiration of organic compounds.

What is the role of a dehydrogenase enzyme?

Dehydrogenases are a group of biological catalysts (enzymes) that mediate in biochemical reactions removing hydrogen atoms [H] instead of oxygen [O] in its oxido-reduction reactions. It is a versatile enzyme in the respiratory chain pathway or the electron transfer chain.
