Kvercetin

Биологическая активность

Quercetin is a plant polyphenol from the flavonoid group, found in many fruits, vegetables, leaves, and grains. It can be used as an ingredient in supplements, beverages, or foods. Quercetin has been reported to inhibit the oxidation of other molecules and hence is classified as an antioxidant. Quercetin contains a polyphenolic chemical substructure that stops oxidation by acting as a scavenger of free radicals that are responsible for oxidative chain reactions. Quercetin also activates or inhibits the activities of a number of proteins.
