Free Radicals
Definition
Free radicals are unstable molecules that can cause damage to the cells in your body, potentially leading to inflammation and various diseases.
Scientific / Technical Definition
Free radicals are atoms or molecules with an unpaired electron. Due to their unpaired electron, they are highly reactive and can initiate chain reactions that damage cellular structures, including DNA, proteins, and cell membranes. This process is known as oxidative stress, which is implicated in aging and a variety of diseases such as cancer, atherosclerosis, and neurodegenerative disorders.
Benefits
- While free radicals can be harmful in excess, they also play vital roles in the body, such as helping to kill pathogens and signaling for important cellular processes.
Examples
- Free radicals are produced naturally in the body during metabolic processes. External sources include cigarette smoke, pollution, radiation, and certain drugs.
Additional Information
- Effects: Free radicals can contribute to the aging process and the development of certain diseases by causing oxidative stress. Balancing free radicals with antioxidants in the body is crucial for maintaining optimal health.
