Reactive Oxygen Species

Reactive Oxygen Species (ROS) are a range of molecules, including free radicals, that are produced during normal cellular respiration and metabolic processes. They are highly reactive and can cause damage to the cells of living organisms, including humans. ROS can act as a signaling molecule in the body, but too much can lead to oxidative stress, which can damage cell structures, proteins and DNA and can disrupt processes such as immune response. Because of this, ROS are associated with many diseases and conditions, including cardiovascular disease, Alzheimer’s disease and cancer. However, they can also have beneficial roles in cellular processes, disease prevention, and even longevity. Research into ROS is ongoing, and understanding their roles can help in studying and developing treatments for many diseases.
