Peroxisome reactive oxygen species
WebMay 20, 2009 · Reactive oxygen species (ROS) can surely be considered as multifunctional biofactors within the cell. They are known to participate in regular cell functions, for example, as signal mediators, but overproduction under oxidative stress conditions leads to deleterious cellular effects, cell death and diverse pathological conditions. WebJul 20, 2024 · Hydogen peroxide, H O O H, is an ROS. Recall peroxides are potent oxidizing agents due to the weakness of the O − O single bond. It is this same weak bond that causes hydrogen peroxide to be dangerous when produced in our bodies, as it can react spontaneously with oxygen or nitrogen nucleophiles and p bonds. Peroxide formed as a …
