In [[enzymology]], a '''flavanone 4-reductase''' ({{EC number|1.1.1.234}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:(2S)-flavan-4-ol + NADP<sup>+</sup> <math>\rightleftharpoons</math> (2S)-flavanone + NADPH + H<sup>+</sup>

Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[(2S)-flavan-4-ol]] and [[nicotinamide adenine dinucleotide phosphate|NADP<sup>+</sup>]], whereas its 3 [[product (chemistry)|products]] are [[(2S)-flavanone]], [[nicotinamide adenine dinucleotide phosphate|NADPH]], and [[hydrogen ion|H<sup>+</sup>]].

This enzyme belongs to the family of [[oxidoreductase]]s, specifically those acting on the CH-OH group of donor with NAD<sup>+</sup> or NADP<sup>+</sup> as acceptor. The [[List of enzymes|systematic name]] of this enzyme class is '''(2S)-flavan-4-ol:NADP<sup>+</sup> 4-oxidoreductase'''. This enzyme participates in [[flavonoid biosynthesis]].
