Definition of a free radical in English English dictionary
- radical
- 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
- free radical
- A molecule that can cause oxidative damage to a cell or tissue Antioxidants are used to destroy free radicals
- free radical
- 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
- free radical
- 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
- an unstable, destructive oxygen molecule created as a normal byproduct of metabolism
- free radical
- 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
- free radical
- 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
- free radical
- A molecule containing an odd number of electrons
- free radical
- 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 radical
- 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
- free radical
- A molecule with an unpaired electron, making it highly reactive
- free radical
- 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)
- free radical
- 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
- free radical
- a species with an unpaired electron
- free radical
- a molecule with an odd, unpaired electron, which is highly unstable and can have distructive effects
- free radical
- 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
- free radical noun
- free radical
- A destructive fragment of oxygen produced as a by-product when cells use oxygen to burn fat
- free radical
- 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
- free radical
- 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
- free radical
- A chemically active, charged atom or complex of atoms containing an excess or deficient number of electrons Radicals seek to transfer electrons from or to other atomic complexes in order to achieve a more stable configuration This process can damage the large molecules within cells See Oxidation
- free radical
- a species with an unpaired electron (22 5)
- free radical
- A highly reactive chemical species carrying no charge and having a single unpaired electron in an orbital
- free radical
- 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
- free radical
- A neutral atom or molecule that contains an unpaired electron
- free radical
- Free radicals are atoms that contain one or more unpaired electrons. Free radicals are believed to be a cause of ageing, heart disease, and some cancers. An atom or group of atoms that has at least one unpaired electron and is therefore unstable and highly reactive. In animal tissues, free radicals can damage cells and are believed to accelerate the progression of cancer, cardiovascular disease, and age-related diseases. an atom or group of atoms with at least one free electron, which combines with other atoms very easily. or radical Molecule containing at least one unpaired electron. Most molecules contain even numbers of electrons, and their covalent bonds normally consist of shared electron pairs. Cleavage of such bonds produces two separate free radicals, each with an unpaired electron (in addition to any paired electrons). They may be electrically charged or neutral and are highly reactive and usually short-lived. They combine with one another or with atoms that have unpaired electrons. In reactions with intact molecules, they abstract a part to complete their own electronic structure, generating new radicals that go on to react with other molecules. Such chain reactions are particularly important in decomposition of substances at high temperatures and in polymerization. In the human body, oxidized (see oxidation-reduction) free radicals can damage tissues. Antioxidant nutrients (e.g., vitamin C, vitamin E, selenium) may reduce these effects. Heat, ultraviolet radiation, and ionizing radiation (see radiation injury) all generate free radicals. They are magnetic, so their properties can be studied with such techniques as magnetic susceptibility and electron paramagnetic resonance measurements
- free radical
- An unstable and highly reactive molecule, bearing an atom with an unpaired electron, that nonspecifically reacts with a variety of organic structures such as DNA The interaction of ionizing radiation with water can generate free radicals in the form of hydroxyl and hydroperoxyl groups that are potent oxidizing agents
- free radical
- This is a substance which can bring about negative changes in the body as a result of its oxidizing effects Some changes include: hardening of the arteries and onset of certain cancers
