Reactive oxygen species (ROS) are a series of molecules, ions, and radicals derived from oxygen that possess remarkable reactivity. They act as signaling molecules when their concentration in cells is within a normal range. When the levels of ROS increase, reaching a concentration in which the antioxidants cannot readily quench them, oxidative stress will affect the cells. These excessive levels of ROS result in direct or indirect ROS-mediated damage of proteins, nucleic acids, and lipids.
