Overview

Reactive oxygen species (ROS) are a group of highly reactive oxygen-containing molecules, including free radicals such as the superoxide anion and hydroxyl radical as well as non-radical species like hydrogen peroxide. They are produced continuously as byproducts of normal cellular respiration and metabolism, particularly in the mitochondria. At controlled levels, ROS act as signalling molecules that regulate processes such as cell growth, immune responses, and gene expression. When their production exceeds the cell's antioxidant defences, however, the resulting oxidative stress can damage proteins, lipids, and DNA and contribute to ageing and a range of diseases. The body counters ROS through enzymatic antioxidants such as superoxide dismutase and catalase and through non-enzymatic antioxidants obtained from the diet, which scavenge radicals and help repair oxidative damage. Maintaining the balance between ROS generation and antioxidant capacity is therefore central to cellular health. Research relevant to this topic examines the antioxidant and radical-scavenging activities of natural compounds and micronutrients, the generation of superoxide and other reactive intermediates during metabolic reactions, and the relationship between oxidative end-products and inflammation. This page brings together peer-reviewed, open-access research relevant to reactive oxygen species, oxidative stress, and Antioxidant Activity.
