In chemistry and biology, reactive oxygen species ( ROS) are highly reactive chemicals formed from diatomic oxygen ( O2 ), water, and hydrogen peroxide. Some prominent ROS are hydroperoxide (O 2 H), superoxide (O 2- ), [1] hydroxyl radical (OH. ), and singlet oxygen. [2] ROS are pervasive because they are readily produced from O 2, which is ...
Mitochondrial ROS ( mtROS or mROS) are reactive oxygen species (ROS) that are produced by mitochondria. [1] [2] [3] Generation of mitochondrial ROS mainly takes place at the electron transport chain located on the inner mitochondrial membrane during the process of oxidative phosphorylation. Leakage of electrons at complex I and complex III from ...

Respiratory burst (or oxidative burst) is the rapid release of the reactive oxygen species (ROS), superoxide anion ( O−. 2) and hydrogen peroxide ( H. 2O. 2 ), from different cell types. This is usually utilised for mammalian immunological defence, but also plays a role in cell signalling. Respiratory burst is also implicated in the ovum of ...
Review of systems. A review of systems ( ROS ), also called a systems enquiry or systems review, is a technique used by healthcare providers for eliciting a medical history from a patient. It is often structured as a component of an admission note covering the organ systems, with a focus upon the subjective symptoms perceived by the patient (as ...

Oxidation response is stimulated by a disturbance in the balance between the production of reactive oxygen species and antioxidant responses, known as oxidative stress. Active species of oxygen naturally occur in aerobic cells and have both intracellular and extracellular sources. These species, if not controlled, damage all components of the ...
