Free Radical Biology

Free Radical Biology studies molecules called free radicals—unstable atoms with unpaired electrons—that are naturally produced during your body's metabolic processes and environmental exposures. These unstable molecules can damage cells, DNA, and tissues by stealing electrons from other molecules, leading to oxidative stress. This damage is associated with aging and various diseases, including cancer and heart conditions. However, the body also has antioxidants—compounds that neutralize free radicals—helping to protect cells. Understanding this balance is key to maintaining health and developing strategies to prevent or treat oxidative damage-related diseases.
