- plural of chelate
- chelate
- to remove heavy metals from the bloodstream using a chelate (such as EDTA)
- chelate
- to form a chelate compound by combining a metal atom to form a ring
- chelate
- a chelate compound
- chelate
- having chelae, or in the form of a chela
- chelate
- (verb - Chemistry) form a chelate with
- chelate
- (noun - Chemistry) a compound containing an organic ligand bonded to a central metal atom at two or more points
- chelate
- (adjective - Zoology) (of an appendage) bearing chelae
- chelate
- Organic substances that cause chelation
- chelate
- having or resembling chelae or claws
- chelate
- {s} having a chela (claw); of a chelate compound (Chemistry)
- chelate
- To form a complex chemical compound in which an ion, usually metallic, is bound into a stable ring structure
- chelate
- a heterocyclic compound having a metal ion attached by coordinate bonds to at least two nonmetal ions
- chelate
- 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
- chelate
- relating to or characterized by chelation
- chelate
- 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
- chelate
- A stable complex of a metal with one or more polydentate ligands For example, calcium complexes with EDTA to form a chelate
- chelate
- Same as Cheliferous
- chelate
- a coordination complex containing rings formed by polydentate ligands
- chelate
- 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
- chelate
- 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
- chelate
- Combining nutrients in an atomic ring that is easy for plants to absorb
- chelate
- (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
- chelate
- {i} (Chemistry) compound composed of and organic ring and metallic ions (such as hemoglobin in the blood, chlorophyll in plants, etc.)
- chelate
- a chemical compound whose molecules contain a closed ring of atoms, of which one is a metal atom
- chelate
- form a chelate, in chemistry
- chelate
- 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
- chelate
- (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
- chelate
- 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
- chelate
- The process of rendering metals unable to combine with other chemicals in water to form stains or discolored water
- chelate
- Chemical compounds able to bind heavy metal salts and make them insoluble in water
