The flavanones, a type of

flavonoid Flavonoids (or bioflavonoids; from the Latin word ''flavus'', meaning yellow, their color in nature) are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans. Chemically, flavonoids ...

Metabolism

The enzyme chalcone isomerase uses a chalcone-like compound to produce a flavanone. Flavanone 4-reductase is an enzyme that uses (2''S'')- flavan-4-ol and NADP⁺ to produce (2''S'')-flavanone, NADPH, and H⁺.

Synthesis

Numerous methods exist for the enantioselective chemical and biochemical synthesis of flavanones and related compounds.
