Introduction: Free radicals are reactive oxygen species that constantly circulate through the
body and occur as a side effect of many reactions that take place in the human body. Under …

The free radical oxidants such as reactive oxygen species, reactive nitrogen species, and
reactive sulfur species are produced inside cells through various metabolic processes. The …

The present review paper focuses on the chemistry of oxidative stress mitigation by
antioxidants. Oxidative stress is understood as a lack of balance between the pro-oxidant …

The role of free radicals in various human ailments is well established. Still, the researchers
continue to emphasize the involvement of free radicals in these disorders. Antioxidants are …

Although reactive oxygen species (ROS) such as superoxide, hydrogen peroxide and
