Cytotoxic reactive oxygen species
Reactive oxygen species (ROS) with the potential to cause cellular damage are produced along with the release of energy. ROS can damage lipids, DNA, RNA, and proteins, which, in theory, contributes to the physiology of aging. ROS are produced as a normal product of cellular metabolism. See more In chemistry, reactive oxygen species (ROS) are highly reactive chemicals formed from diatomic oxygen (O2). Examples of ROS include peroxides, superoxide, hydroxyl radical, singlet oxygen, and alpha-oxygen See more Effects of ROS on cell metabolism are well documented in a variety of species.
