Role of Oxidative Stress in Parkinson’s Disease

Introduction Our body requires ATP, which is generated by reducing O2 to H2O through oxidative phosphorylation(OxPhos) in mitochondria (Jarmuszkiewicz, et al., 2015). During this process, a group of reactive metabolites including free radicals(FR)(e.g. O2●-, OH●) and non-radicals(e.g. H2O2) are generated. They are grouped as reactive oxygen species(ROS) (Rao, et al., 2011). FR are groups of atoms orbited… Continue reading Role of Oxidative Stress in Parkinson’s Disease
