In enzymology, a D-arabinitol 4-dehydrogenase (EC 1.1.1.11) is an enzyme that catalyzes the chemical reaction

D-arabinitol + NAD+ D-xylulose + NADH + H+

Thus, the two substrates of this enzyme are D-arabinitol 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 D-arabinitol:NAD+ 4-oxidoreductase. Other names in common use include D-arabitol dehydrogenase and arabitol dehydrogenase. This enzyme participates in pentose and glucuronate interconversions and fructose and mannose metabolism.
