WebMay 9, 2013 · ROS, key signaling molecules during cell signaling and homeostasis, are reactive species of molecular oxygen. ROS constitute a pool of oxidative species including superoxide anion ( ), hydroxyl radical (OH • ), hydrogen peroxide (H 2 O 2 ), singlet oxygen ( 1 O 2 ), and hypochlorous acid (HOCl). WebGeneration of reactive oxygen species (ROS) is inevitable for aerobic organisms and, in healthy cells, occurs at a controlled rate. Under conditions of oxidative stress, ROS production is dramatically increased, resulting in subsequent alteration of membrane lipids, proteins, and nucleic acids.
