Free radical listen (free RA-dih-kul) A type of unstable molecule that is made during normal cell metabolism (chemical changes that take place in a cell). Is there a connection between free radicals and aging? If so, how do we stop free radicals from destroying cells? Learn about free radicals and aging. Free radicals Highly chemically active atoms or group of atoms capable of free existence, under special conditions, for very short periods, each having at least one unpaired elect. Free radicals Introduction of free radicals Formation of free radicals Stabilization of free radicals Moses Gomberg. A radical (often, but unnecessarily called a free radical) is an atom or group of atoms that have one or more unpaired electrons. Radicals can have positive, negative or neutral charge. They are formed as necessary. What Is A Free Radical? Free radicals may be formed through natural human physiological processes as well as from the environment. They may be the result of diet, stress, smoking, alcohol, exercise. Free radicals are molecules with unpaired electrons. They rob other cells of electrons, causing damage and contributing to many diseases. The free radical theory of aging was conceived by Denham Harman in the 1950s, when prevailing scientific opinion held that free radicals were too unstable to exist in biological systems. This was also before anyone. Antioxidants and Free radicals. Antioxidants are intimately involved in the prevention of cellular damage -- the common pathway for cancer, aging, and a variety of diseases. The scientific community has begun to unveil some of.
