Excessive reactive nitrogen species (RNS) and reactive oxygen species (ROS), such as H 2 O 2 (hydrogen peroxide), HO − (hydroxyl radical), HOO − (hidroperoxil), NO − (nitric oxide radical), NO 2− ...

The build-up of reactive oxygen species to a high level inside cells is known as oxidative stress. This causes damage to proteins, DNA and RNA and can even result in cell death. ROS biomolecules have ...
