Redox Biology is the study of reduction-oxidation (redox) reactions in biological systems. These reactions involve the transfer of electrons between molecules, which can affect cellular processes, energy production, and signaling pathways. Redox reactions play a crucial role in maintaining cellular health and function, influencing everything from metabolism to the response to stress. In living organisms, antioxidants help protect cells from damage caused by reactive oxygen species (ROS), which are byproducts of metabolism. Understanding redox biology is essential for exploring various health conditions, including cancer, neurodegenerative diseases, and inflammation, as it provides insights into how cells manage oxidative stress and maintain balance.
