In enzymology, sorbitol-6-phosphate dehydrogenase (EC 1.1.1.140) is an enzyme that catalyzes the chemical reaction

 
 
 
H+
 
H+
 
 

The two substrates of this enzyme are D-sorbitol 6-phosphate and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are fructose 6-phosphate (shown in its open-chain form), reduced NADH, and a proton.[1][2][3]

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 D-sorbitol-6-phosphate:NAD+ 2-oxidoreductase. Other names in common use include ketosephosphate reductase, ketosephosphate reductase, D-sorbitol 6-phosphate dehydrogenase, D-sorbitol-6-phosphate dehydrogenase, sorbitol-6-P-dehydrogenase, and D-glucitol-6-phosphate dehydrogenase. This enzyme participates in fructose and mannose metabolism.
