1,5-anhydro-D-glucitol + NADP+ 1,5-anhydro-D-fructose + NADPH + H+

Thus, the two substrates of this enzyme are 1,5-anhydro-D-glucitol and NADP+, whereas its 3 products are 1,5-anhydro-D-fructose, NADPH, 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 1,5-anhydro-D-glucitol:NADP+ oxidoreductase.
