  |  | Definition | ChEBI: (-)-catechin is the (-)-enantiomer of catechin. It has a role as a metabolite. It is an enantiomer of a (+)-catechin. |  | General Description | This substance is a primary reference substance with assigned absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities). The exact value can be found on the certificate. Produced by PhytoLab GmbH & Co. KG |  | Biochem/physiol Actions | Catechins have wide biological functionality. They induce antiviral and anticancer activities. Catechins also play a key role in regulating carbohydrate and lipid metabolism. It prevents fat accumulation. |
