Retinol dehydrogenase

Retinol dehydrogenase

In enzymology, a retinol dehydrogenase is an enzyme that catalyzes the chemical reaction

retinol + NAD+ rightleftharpoons retinal + NADH + H+

Thus, the two substrates of this enzyme are retinol and NAD+, whereas its 3 products are retinal, 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 retinol:NAD+ oxidoreductase. Other names in common use include retinol (vitamin A1) dehydrogenase, MDR, microsomal retinol dehydrogenase, all-trans retinol dehydrogenase, retinal reductase, and retinene reductase. This enzyme participates in retinol metabolism.
