Reactive Oxygen Species
Reactive Oxygen Species (ROS) are a group of highly reactive molecules that play a crucial role in the physiological functioning of all living organisms. These molecules include oxygen radicals, such as superoxide and hydroxyl radicals, as well as non-radical derivatives of oxygen, like hydrogen peroxide. ROS are formed as a by-product of normal metabolic processes or due to environmental influences like radiation and pollution. ROS act as messengers within the cell, serving both as signals for cellular processes such as gene expression and as defensive enzymes to protect us from pathogens. While ROS play an essential role in maintaining health, an excessive amount can lead to significant cell damage, oxidative stress and aging, and even diseases like cancer. ROS are thus studied extensively with respect to the development and treatment of diseases, as well as in many other areas of research. Understanding the role that these molecules play in the body can provide insights into how to prevent and potentially treat a variety of diseases.
