They perform key roles in lipid metabolism and the reduction of reactive oxygen species. Peroxisomes are involved in the catabolism of very long chain...

The metabolism of some chemicals results in the production of reactive oxygen species (ROS), which is a possible mechanism of genotoxicity. This is seen...

lipoxygenase releases reactive oxygen species (ROS) and the initial products in eicosanoid generation are themselves highly reactive peroxides. LTA4 can...

anthracyclines can undergo redox reactions to generate excessive reactive oxygen species (ROS) in the presence of oxidoreductive enzymes such as cytochrome...
