Excerpt

Reactive oxygen species (ROS) is a term used to describe a number of reactive molecules and free radicals derived from molecular oxygen [1]. ROS are produced in normal biological processes in cells by means of either enzymatic or nonenzymatic mechanisms and play beneficial and adverse roles in an organism [2]. Oxidative stress, an imbalance toward the pro-oxidative state, is caused by the presence of free radicals or radical-generating agents in concentrations that overwhelm natural radical-blocking or radical-scavenging mechanisms [1]. Under oxidative stress conditions, excessive ROS can damage DNA, cellular proteins, and lipids, leading to fatal lesions in cells that contribute to carcinogenesis [3]. …
