Mannitol dehydrogenase

In enzymology, mannitol dehydrogenase is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are D-mannitol and oxidised nicotinamide adenine dinucleotide. Its products are D-mannose, reduced NADH and a proton.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD⁺ or NADP⁺ as acceptor. The systematic name of this enzyme class is mannitol:NAD⁺ 1-oxidoreductase. Other names in common use include MTD, and NAD⁺-dependent mannitol dehydrogenase.
