(Redirected from Flavanones)

The flavanones, a type of flavonoids, are various aromatic, colorless ketones derived from flavone that often occur in plants as glycosides.^[1]^[2]

List of flavanones

The enzyme chalcone isomerase uses a chalcone-like compound to produce a flavanone.

Flavanone 4-reductase is an enzyme that uses (2S)-flavan-4-ol and NADP⁺ to produce (2S)-flavanone, NADPH, and H⁺.

Numerous methods exist for the enantioselective chemical and biochemical synthesis of flavanones and related compounds.^[3]
