تعريف chelate في الإنجليزية الإنجليزية القاموس.: to remove heavy metals from the bloodstream using a chelate (such as EDTA); to form a chelate compound by combining a metal atom to form a ring; a chelate compound; having chelae, or in the form of a chela; (verb - Chemistry) form a chelate with; (noun - Chemistry) a compound containing an organic ligand bonded to a central metal atom at two or more points; (adjective - Zoology) (of an appendage) bearing chelae; Organic substances that cause chelation; having or resembling chelae or claws; {s} having a chela (claw); of a chelate compound (Chemistry); To form a complex chemical compound in which an ion, usually metallic, is bound into a stable ring structure; a heterocyclic compound having a metal ion attached by coordinate bonds to at least two nonmetal ions; a heterocyclic compound having a metal ion attached by coordinate bonds to at least two nonmetal ions form a chelate, in chemistry having or resembling chelae or claws relating to or characterized by chelation; relating to or characterized by chelation; A coordination complex in which more than one atom or molecule (often an organic compound) binds to a metal In the environment, chelation effectively removes the metal: it is no longer available for chemical interactions or to biota See Complexation; A stable complex of a metal with one or more polydentate ligands For example, calcium complexes with EDTA to form a chelate; Same as Cheliferous; a coordination complex containing rings formed by polydentate ligands; Organic chemical that forms ring compound in which a metal is held between two or more atoms strongly enough to diminish the rate at which it becomes fixed by soil, thereby making it more available for plant and microbial uptake; A form of a mineral or trace mineral whereby it is bound, usually synthetically, to a carbon based or "organic" substance Chelates can allow high concentrations of certain elements to be more readily broken down into ionic form and absorbed when compared to other minerals which are bound to other non-organic substances Chelates, however, tend not to be naturally balanced; Combining nutrients in an atomic ring that is easy for plants to absorb; (Pronounced KEY-late) - also called sequester - It is the process of preventing metals in the water from combining with other components in water to form colored precipitates that stain the pool walls and bottom or produce colored water; {i} (Chemistry) compound composed of and organic ring and metallic ions (such as hemoglobin in the blood, chlorophyll in plants, etc.); a chemical compound whose molecules contain a closed ring of atoms, of which one is a metal atom; form a chelate, in chemistry; A combination of a metal ion and an organic molecule which results in making the metal ion less reactive with other chemical species in water or in a soil solution; (Pronounced KEY-late) - also called sequester - It is the process of preventing metals in the water from combining with other compon- ents in water to form colored precipitates that stain the pool walls and bottom or produce colored water; Any of a class of coordination or complex compounds consisting of a central atom of a metal (usually a transition element) attached to a large molecule (ligand). Any ligand that can bind to the metal at two or more points to form a ring structure, more stable than a nonchelated compound of the same general chemical formula, is a chelating agent. The process of binding to the metal is called chelation. Chelating agents such as EDTA salts are used in medicine to remove toxic metals (e.g., lead, cadmium) from the body. Others are used in analysis as indicators and in industry to extract metals. The iron-binding porphyrin group in hemoglobin, the magnesium-binding porphyrin in chlorophyll, and the cobalt-binding porphyrin in vitamin B12 are natural chelators; The process of rendering metals unable to combine with other chemicals in water to form stains or discolored water; Chemical compounds able to bind heavy metal salts and make them insoluble in water
chelate compound: a cyclic compound in which a metal atom is bonded to at least two other atoms
chelated: bound with one or more chelates
chelated: Simple past tense and past participle of chelate
chelation: the use of this process to remove metal ions from solution, especially to counter poisoning by heavy metals
chelator: A chelating agent
chelated: relating to or characterized by chelation
chelates: plural of chelate
chelating: Having the ability to undergo chelation
chelation: Chemical weathering process that involves the extraction or metallic cations from rocks and minerals by chelates
chelation: therapy to remove excess iron which builds up in the blood of frequent transfusion recipients
chelation: A chemical complexing (forming or joining together) of metallic cations (such as copper) with certain organic compounds, such as EDTA (ethylene diamine tetracetic acid) Chelation is used to prevent the precipitation of metals (copper) Also see sequestration
chelation: {i} (Chemistry) creation of chelates (compound made of metallic and nonmetallic ions)
chelation: the process by which both naturally occurring and artificial agents can be used as sequestering agents, thereby making radionuclides and other chemicals in a particular media available for transfer to another environment Artificial chelating agents such as EDTA have a wide variety of industrial uses, and are often used to remove radioactive contamination Unfortunately, natural chelating agents and chelating processes make plutonium oxide from stratospheric fallout and nuclear accidents which is usually in a biologically unreactive state in soils and sediment much more biologically available for uptake in pathways to human consumption Almost no information is available about the long-term mobilization of plutonium isotopes by naturally occurring chelating agents (See Hanson, 1980, Section 10)
chelation: the process of forming a ring by forming one or more hydrogen bonds (medicine) the process of removing a heavy metal from the bloodstream by means of a chelate as in treating lead or mercury poisoning
chelation: the formation of a polydentate chelate compound from a metal salt
chelation: Treatment of heart and other circulatory conditions through EDTA, Vitamins and Minerals, which carry out from the body, heavy metals like lead, and arsenic, as well as other foreign substances It is a clinically proven therapy for metal poisoning

chelation: the process of forming a closely associated complex with a metal in which the meatl is surrounded by and multiply bound to part of an organic structure, thereby usually altering both the chemical reactivity and transport properties of the metal
chelation: A reaction between a metallic ion and an organic compound that removes the metallic ion from solution Chelation is a natural reaction in most soils and is enhanced by organic matter, especially humus Chelation is similar to cation exchange, except that it usually is more stable in holding ions Most of the trace cation nutrients are held in soil by chelation (copper, iron, manganese)
