Web10 (Reactive Oxygen Species) disebut antioksidan.Berbagai jaringan yang dapat mengalami kerusakan akibat ROS (Reactive Oxygen Species) diantaranya adalah Deoxyribo Nucleid Acid (DNA), lipid dan protein. Interaksi ROS (Reactive Oxygen Species) dengan basa dari DNA dapat merubah struktur kimia DNA, apabila tidak direparasi akan mengalami mutasi … 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. The reduction of … See more Effects of ROS on cell metabolism are well documented in a variety of species. These include not only roles in apoptosis (programmed cell death) but also positive effects such as the induction of host defence genes and mobilization of ion transporters. … See more Exposure of spermatozoa to oxidative stress is a major causative agent of male infertility. Sperm DNA fragmentation, caused by oxidative stress, appears to be an important factor in the etiology of male infertility. A high level of the oxidative DNA damage See more Endogenous sources ROS are produced by biochemical reactions that occur during the processes of respiration and photosynthesis in organelles such as See more Superoxide dismutase Superoxide dismutases (SOD) are a class of enzymes that catalyzes the dismutation of superoxide into oxygen and hydrogen peroxide. As such, they are an important antioxidant defense in nearly all cells exposed to oxygen. … See more According to the free radical theory of aging, oxidative damage initiated by reactive oxygen species is a major contributor to the … See more ROS are constantly generated and eliminated in the biological system and are required to drive regulatory pathways. Under normal physiological conditions, cells control ROS … See more

Reactive nitrogen species (RNS) are a family of nitrogen moieties associated with oxygen. They are generated when nitric oxide (NO) produced either exogenously or endogenously interacts with reactive oxygen species like superoxide () and hydrogen peroxide (H 2 O 2) ( Auger et al., 2011 ).
