(Gıda,İnşaat) free radical

any molecule, ion or atom that has one or more unpaired electrons; they are generally highly reactive and often only occur as transient species

A molecule that can cause oxidative damage to a cell or tissue Antioxidants are used to destroy free radicals

A molecule containing an unpaired electron, typically highly unstable and reactive Free radicals can damage the molecular machinery of biological systems, leading to cross-linking and mutation

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

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

short-lived form of compounds that exist with an unpaired electron in the outer electron shell; to complete the electron pair the compound seeks an additional electron from another molecule often from electron dense areas of the cell such as the nucleus or the cell membrane

An atom or group of atoms broken away from a stable compound by application of external energy, and, although containing unpaired electrons, remaining free for transitory or longer periods

A molecule containing an odd number of electrons

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

A molecule with an unpaired electron In the body, free radicals are generated by both enzymatic and chemical reactions, including the metabolism of fats Free radicals are believed to be involved in extensive damage to the body, including aging cancer, heart disease and arthritis

A molecule with an unpaired electron, making it highly reactive

a molecule that contains at least one unpaired electron Free radicals are highly reactive and bind with other molecules, thus disrupting normal cellular processes and causing cellular damage (oxidative stress)

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

a species with an unpaired electron

a molecule with an odd, unpaired electron, which is highly unstable and can have distructive effects

a highly chemically reactive atom, molecule or molecular fragment with a free or unpaired electron 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)

free radical noun

A destructive fragment of oxygen produced as a by-product when cells use oxygen to burn fat

molecules containing an odd number of electrons resulting in an open bond or half bond, making them highly reactive and as a result, potentially destructive

an atom or group of atoms with at least one unpaired electron; in the body it is usually an oxygen molecule than has lost an electron and will stabilize itself by stealing an electron from a nearby molecule; "in the body free radicals are high-energy particles that ricochet wildly and damage cells
