In enzymology a galactose 1-dehydrogenase (NADP+) (EC 1.1.1.120) is an enzyme that catalyzes the chemical reactionD-galactose + NADP+ D-galactonolactone + NADPH + H+Thus the two substrates of this enzyme are D-galactose and NADP+ whereas its 3 products are D-galactonolactone NADPH 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.
