ROS sources ROS are unstable oxygen-containing molecules that include radical ROS (e.g., superoxide anions [O 2 ], hydroxyl radicals [OH], peroxyl radical [ROO], alkoxyl radical [RO], carbonate radical [CO 3 ], hydroperoxyl radical [HO 2 ], nitric oxide [NO], and nitrogen dioxide [NO 2 ]) and non-radical ROS (e.g., hydrogen peroxide [H 2 O 2 ], peroxynitrite [ONOO ], hypochlorous acid [HOCl], singlet oxygen [ 1 O 2 ], ozone [O 3 ], and nitrocarbonate [ONOOCO 2 ]) [11] (Table 1)
