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