In enzymology, an aldose 1-dehydrogenase (EC 1.1.1.121) is an enzyme that catalyzes the chemical reaction

D-aldose + NAD⁺ ${\displaystyle \rightleftharpoons }$ D-aldonolactone + NADH + H⁺

Thus, the two substrates of this enzyme are D-aldose and NAD⁺, whereas its 3 products are D-aldonolactone, 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-aldose:NAD⁺ 1-oxidoreductase. Other names in common use include aldose dehydrogenase, and dehydrogenase, D-aldohexose.
