L-galactose 1-dehydrogenase

L-galactose 1-dehydrogenase (, L-GalDH, L-galactose dehydrogenase) is an enzyme with the systematic name L-galactose:NAD+ 1-oxidoreductase. This enzyme catalyses the following chemical reaction:


 * L-galactose + NAD+ $$\rightleftharpoons$$ L-galactono-1,4-lactone + NADH + H+

The enzyme catalyses a step in the ascorbate biosynthesis in higher plants.
