In enzymology a mannitol dehydrogenase (EC 1.1.1.255) is an enzyme that catalyzes the chemical reactionD-mannitol + NAD+ 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.
