In enzymology, a galactitol 2-dehydrogenase (EC 1.1.1.16) is an enzyme that catalyzes the chemical reaction

galactitol + NAD+ D-tagatose + NADH + H+

Thus, the two substrates of this enzyme are galactitol and NAD+, whereas its 3 products are D-tagatose, 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 galactitol:NAD+ 2-oxidoreductase. This enzyme is also called dulcitol dehydrogenase. This enzyme participates in galactose metabolism.

NADH dehydrogenase is an enzyme that converts nicotinamide adenine dinucleotide (NAD) from its reduced form (NADH) to its oxidized form (NAD+). Members of the NADH dehydrogenase family and analogues are commonly systematically named using the format NADH:acceptor oxidoreductase. The chemical reaction these enzymes catalyze is generally represented with the following equation:
