In enzymology, omega-hydroxydecanoate dehydrogenase () is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are 10-hydroxydecanoic acid and oxidised nicotinamide adenine dinucleotide (NAD<sup>+</sup>). Its products are 10-oxodecanoic acid, reduced NADH, and a proton.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD<sup>+</sup> or NADP<sup>+</sup> as acceptor. The systematic name of this enzyme class is 10-hydroxydecanoate:NAD<sup>+</sup> 10-oxidoreductase.
