In enzymology, a D-sorbitol dehydrogenase (acceptor) () is an enzyme that catalyzes the chemical reaction D-sorbitol + acceptor L-sorbose + reduced acceptor Thus, the two substrates of this enzyme are D-sorbitol and acceptor, whereas its two products are L-sorbose and reduced acceptor. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with other acceptors. The systematic name of this enzyme class is D-sorbitol:acceptor 1-oxidoreductase. This enzyme is also called D-sorbitol:(acceptor) 1-oxidoreductase. This enzyme participates in fructose and mannose metabolism. It employs one cofactor, FAD. References EC 1.1.99 Flavoproteins Enzymes of unknown structure
