Reactive oxygen species in cell signaling
WebJun 1, 2024 · ROS are short-lived chemically reactive radicals, such as hydrogen peroxide (H 2 O 2 ), superoxide (O 2 − ), hydroxyl radical (OH ), and singlet oxygen. ROS are generated from oxygen (O2) by several intracellular mechanisms. Mitochondria mainly generate superoxide by reducing one electron of O 2. WebReactive oxygen species (ROS) have recently been identified as the molecular intermediates in the translation of mechanical stimuli to cellular response. Different signal transduction …
