In enzymology, an L-xylulose reductase (EC 18.104.22.168) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are xylitol and NADP+, whereas its 3 products are D-xylulose, NADPH, and H+.
Xylitol (Note conversion of ketone to alcohol)
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:NADP+ 2-oxidoreductase (L-xylulose-forming).
A deficiency is responsible for pentosuria.
