In enzymology a lactaldehyde dehydrogenase (EC 1.2.1.22) is an enzyme that catalyzes the chemical reaction(S)-lactaldehyde + NAD+ + H2O (S)-lactate + NADH + 2 H+The 3 substrates of this enzyme are (S)-lactaldehyde NAD+ and H2O whereas its 3 products are (S)-lactate NADH and H+.This enzyme belongs to the family of oxidoreductases specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor.
