Oxidative stress is the condition when the production of free radicals and antioxidant mechanisms, to detoxify their damaging effects, are imbalanced. Under such conditions, the levels of reactive oxygen species (ROS) rise and may result in some damage. ROS includes hydrogen peroxide, singlet oxygen, superoxide radical, and hydroxyl radical.
