In enzymology a D-xylulose reductase (EC 1.1.1.9) is an enzyme that catalyzes the chemical reactionxylitol + NAD+ D-xylulose + NADH + H+Thus the two substrates of this enzyme are xylitol and NAD+ whereas its 3 products are D-xylulose 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 xylitol:NAD+ 2-oxidoreductase (D-xylulose-forming).
