5-dehydro-D-fructose
 

The two substrates of this enzyme are D-fructose (shown in its keto form) and oxidised nicotinamide adenine dinucleotide phosphate (NADP+). ts products are 5-dehydro-D-fructose, reduced NADPH, and a proton.[1][2][3]

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