Thus, the two substrates of this enzyme are 1,2-propanediol and NADP+, whereas its 3 products are L-lactaldehyde, 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. The systematic name of this enzyme class is propane-1,2-diol:NADP+ oxidoreductase. Other names in common use include lactaldehyde (reduced nicotinamide adenine dinucleotide phosphate), reductase, NADP+-1,2-propanediol dehydrogenase, propanediol dehydrogenase, 1,2-propanediol:NADP+ oxidoreductase, and lactaldehyde reductase (NADPH).
