- d-iditol + NAD+ d-sorbose + NADH + H+
Thus, the two substrates of this enzyme are d-iditol and NAD+, whereas its 3 products are d-sorbose, 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 d-iditol:NAD+ 2-oxidoreductase. This enzyme is also called d-sorbitol dehydrogenase. This enzyme participates in pentose and glucuronate interconversions and fructose and mannose metabolism.
