In enzymology, sorbose 5-dehydrogenase (NADP+) (EC 1.1.1.123) is an enzyme that catalyzes the chemical reaction

5-dehydro-D-fructose
 

The two substrates of this enzyme are L-sorbose and oxidised nicotinamide adenine dinucleotide phosphate (NADP+). Its products are 5-dehydro-D-fructose, reduced NADPH, and a proton.[1][2]

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 L-sorbose:NADP+ 5-oxidoreductase. Other names in common use include 5-ketofructose reductase, 5-keto-D-fructose reductase, sorbose (nicotinamide adenine dinucleotide phosphate) dehydrogenase, reduced nicotinamide adenine dinucleotide phosphate-linked, reductase, and sorbose 5-dehydrogenase (NADP+).
