Leukoantocijanidin reduktaza (EC 1.17.1.3, leuocijanidinsk reduktaza) je enzim sa sistematskim imenom (2R,3S)-katehin:NADP+ 4-oksidoreduktaza.[1][2] Ovaj enzim katalizuje sledeću hemijsku reakciju
- (2R,3S)-katehin + NADP+ + H2O 2,3-trans-3,4-cis-leuocijanidin + NADPH + H+
Ovaj enzim katalizuje sintezu katehina, katehin-4beta-ola (leuocijanidina) i srodnih flavan-3-ola: afzelehina i galokatehina.
