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

+ NAD+
 
 
 
H+
Mannitol dehydrogenase
 
H+
 
+ NADH
 

The two substrates of this enzyme are D-mannitol and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are D-mannose, reduced NADH and a proton. [1] [2] [3] [4]

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.
