pOnce the existence of free radicals was proven, an avalanche of studies on free radical-mediated biological processes ensued. The study of reactive oxygen and nitrogen species ROS and RNS is center stage in biological free radical investigations. Written by a biochemist, strongSignaling Mechanisms of Oxygen and Nitrogen Free Radicalsstrong discusses the regulatory functions of ROS and RNS in physiological and pathophysiological states.pbrbrppbrbrpAn exploration of the main questions of signaling mechanisms of reactive oxygen and nitrogen species in enzymatic processes, this book draws attention to the chemical mechanisms of these reactions. It elucidates the differences between signaling functions and damaging effects of ROS and RNS in biological systems. The text also covers free radical signaling processes catalyzed by enzymes, producers of superoxide and nitric oxide that are able to use produced ROS and RNS as signaling species in their own catalytic processes. It then examines RO
