Mannitol dehydrogenase

In enzymology, a mannitol dehydrogenase (EC 1.1.1.255) is an enzyme that catalyzes the chemical reaction

D-mannitol + NAD⁺ ${\displaystyle \rightleftharpoons }$ D-mannose + NADH + H⁺

Thus, the two substrates of this enzyme are D-mannitol and NAD⁺, whereas its 3 products are D-mannose, NADH, and H⁺.

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.
