The term "oxidative stress" refers to the imbalance between oxidants and antioxidants in favor of oxidants that could potentially lead to damage. While it is well accepted that a low level of production of free radicals (ROS) is necessary to maintain the physiological function, on the other hand it is believed that an excessive formation of ROS causes damage in the biomolecules. ROS defense systems include endogenous / exogenous antioxidants, scavenger enzymes and chelating proteins for pro-oxidant metals. The damage of lipids, proteins and nucleic acids, at the cellular...
