Inactivation of Hydrogen Peroxide by Vitamin A, Vitamin C, Vitamin E, and Other Commercial Items Through Peroxidase-Catalyzed Reaction

Abstract

Reactive oxygen species (ROS), such as hydrogen peroxide (H₂O₂), are highly reactive and can inhibit the normal function of cells. Due to the damage ROS can cause, much interest has been generated around the effects of antioxidant supplements, which could potentially prevent or slow down ROS in the body. In this study, a variety of antioxidants were evaluated for their ability to inactivate H₂O₂ in a peroxidase-catalyzed reaction. Six of the fourteen antioxidants were significantly effective at inactivating H₂O₂ compared to the control. This study should be used to further understand how antioxidant supplements could be beneficial in the human diet.
