Flavonoids are a group of phytonutrients found in all plants on the planet. Functions of these chemicals in plants include UV protection, defense against invasive pathogens, pigmentation, and signaling in symbiosis. This group of chemicals can be broken down further into subgroups based on the makeup of their chemical structures. In foods, flavonoids are full of natural antioxidants and can be found in a multitude of food types.
Chemical structures
All flavonoids consist of phenolic and pyrane rings and are generally insoluble. [2] Flavonoids differ in the arrangement of hydroxyl, methoxy, and glycosidic groups and form six main subgroups.
