Destructive and unstable oxygen atom or a reactive molecule with a "free" (unpaired) electron. Free radicals are believed to cause aging, cancer, cardiovascular disease, etc. Some free radicals are produced as a normal part of metabolism in the cell's mitochondria. Additional free radicals are also produced by the effects on the body of stress, exposure to ultraviolet rays of the sun, tobacco smoking and second-hand smoke, environmental pollution, exposure to radiation, etc. Free radicals are formed when food is cooked in heated fats and oils.

a molecule that contains at least one unpaired electron. Free radicals (reactive oxygen species) are a byproduct of normal metabolism. They are highly reactive and bind with electrons from other molecules, potentially initiating chain reactions as successive molecules lose and gain electrons. The robbing of electrons by free radicals can disrupt normal cellular processes and cause cellular damage (oxidative stress). See also antioxidant, oxidation.

an atom or atom group with an unpaired electron and no charge that interacts readily with nearby molecules. By interacting with cellular components, free radicals may cause cellular and genetic damage, and their inolvement has been implicated in several diseases as atherosclerosis, HIV/AIDS, cancer, chronic fatigue syndrome, asthma, arthritis, cystic fibrosis, multiple sclerosis, fibromyalgia, and other immune disorders. Free radicals are generated by smoking, environmental pollutants, exposure to UV radiation, and also occur naturally in the body as a result of metabolic processes. Ffree radical damage may be countered with antioxidants.

Free radicals are aggressive atoms or molecules that cause permanent damage when they react with cell components. They are highly reactive because they have unpaired electrons. Free radicals attack the nearest stable molecule and "steal" its electron, thereby oxidizing the molecule. Research shows that free radicals are associated with premature aging and the degenerative diseases.

A highly reactive substance which, in some circumstances can lead to undesirable chemical changes in the body through oxidisation, e.g. hardening of the blood vessels and development of cancer.

A chemical component that contains a free electron which covalently bonds with a free electron on another molecule.

a radical in its uncombined state; an atom or atom group carrying an unpaired electron and no charge (usually an oxygen molecule). Free radicals are very reactive and unstable and do not stay in this transient state for very long. Free radicals react with cell components, stealing their electrons and thus creating more free radicals and causing damage.

An atom of group of atoms which have an unpaired electron, making it extremely unstable and liable therefore to undergo further reactions.

An unstable and highly reactive atom that carries an unpaired electron (e.g., oxygen molecules formed in the process of metabolism). Because they are highly reactive, free radicals can damage cells, possibly leading to numerous diseases.

Free radicals are produced in many different ways such as, normal metabolic processes, ultraviolet radiation from the sun, nuclear radiation and the breakdown in the body of spoiled fats. Free radicals have been implicated in aging, cancer, cardiovascular disease and other kinds of damage to the body, (see antioxidants).

A highly reactive chemical that often contains oxygen and is produced when molecules are split to give products that have unpaired electrons (a process called oxidation). Free radicals can damage important cellular molecules such as DNA or lipids or other parts of the cell.

A free radical is a molecule with an odd number of electrons. Free radicals do not have a completed octet and often undergo vigorous redox reactions. Free radicals produced within cells can react with membranes, enzymes, and genetic material, damaging or even killing the cell. Free radicals have been implicated in a number of degenerative conditions, from natural aging to Alzheimer's disease.

an unstable, destructive oxygen molecule created as a normal byproduct of metabolism.

Any molecular fragment containing an unpaired electron. Such fragments are often very reactive, reacting with nearby molecules as fast as they encounter them. Radicals formed on the surface of catalysts may be much more stable and able to undergo more selective chemistry. This is due to the stabilizing influence of the surface.

Free radical refers to a highly reactive molecule that can bind to and destroy the body's cellular compounds. Most free radicals in the body are toxic forms of oxygen molecules. Similar to the formation of rust, oxygen in its toxic state can damage molecules in our bodies. The body tends to produce more free radicals with age, and they are believed to play a role in the onset of degenerative diseases, as well as heart disease and cancer.

A grouping of atoms that normally exists in combination with other atoms but can sometimes exist independently. Generally very reactive in a chemical sense.

A free radical is an atom or group of atoms that has at least one unpaired electron. Because another element can easily pick up this free electron and cause a chemical reaction, these free radicals can effect dramatic and destructive changes in the body. Free radicals are activated in heated and rancid oils and by radiation in the atmosphere, among other things.

Any atom or molecule that has one or more unpaired electrons and is capable of independent existence.

A chemical species that possesses an unpaired electron. These compounds, such as chlorine monoxide (ClO), hydroxyl radical (OH), and nitric oxide (NO), are characterized by a high chemical reactivity. Free radicals are often generated in the atmosphere from the photodissociation of more stable species. Their subsequent chemistry is central to such environmental issues as stratospheric ozone depletion and tropospheric oxidant production.

A molecule that is unstable because it is missing an electron (a negatively charged subatomic particle), which makes it highly reactive and able to damage other molecules and, therefore, cells in the body.
