Cover Story: Polyphenols, found in fruit and vegetables, are shown to perform the same chemical reaction as the metalloprotein superoxide dismutase enzymes (Cu, Zn, and Mn), which catalyze dismutation of the superoxide anion free radical (O2) into H2O2 and O2, as shown in (A), but without a metal or protein. This review describes the interaction between the superoxide radical and several polyphenols. Besides superoxide reactivity with a polyphenol H(hydroxyl), resulting in H2O2 formation, an additional polyphenol ring π–π interaction affects the transfer of the unpaired superoxide electron to the polyphenol ring and the release of a molecule of O2, as shown in (B). View this paper
