Anagram & Information om | Engelska ordet CHELATE

Exempel på hur du använder CHELATE i en mening

• Arsenic and some other heavy metals act by chelating with adjacent thiol residues on metabolic enzymes, creating a chelate complex that inhibits the affected enzyme's activity.
• It is a very strong iron chelator and in the body it is likely that the iron chelate is the active species that quenches the active site tyrosyl radical required by ribonucleotide reductase for its enzymatic activity.
• An active moiety is a molecule or ion, excluding those appended portions of the molecule that cause the drug to be an ester, salt (including a salt with hydrogen or coordination bonds), or other noncovalent derivative (such as a complex, chelate, or clathrate) of the molecule, responsible for the physiological or pharmacological action of the drug substance.
• Crangonid shrimps' first pair of pereiopods have partially chelate claws that they use to capture their prey.
• A sequestrant forms chelate complexes with polyvalent metal ions, especially copper, iron and nickel.
• The biuret reagent is made of sodium hydroxide (NaOH) and hydrated copper(II) sulfate, together with potassium sodium tartrate, the latter of which is added to chelate and thus stabilize the cupric ions.
• Although it is not widely cultivated, Alloxylon flammeum has proven to be by far the most hardy and adaptable (as well as the showiest) member of the genus Alloxylon, Yellowing of new leaves may indicate chlorosis from iron deficiency and can be remedied with iron chelate or iron sulphate.
• Other instigators are ureides, semicarbazides and thiosemicarbazides, which are believed to chelate the prosthetic Cu(II)-bipyridine cofactor complex in the enzyme lysyl oxidase.
• The Bailar twist is a mechanism proposed for the racemization of octahedral complexes containing three bidentate chelate rings.
• The Ray–Dutt twist is a mechanism proposed for the racemization of octahedral complexes containing three bidentate chelate rings.
• The pigments biliverdin and its zinc chelate give a green or blue ground color, and protoporphyrin produces reds and browns as a ground color or as spotting.
• It reacts with a variety of electrophiles at the 3-positions of the chelate rings, giving the corresponding bromo-, nitro-, and formyl-substituted derivatives.
• Then soaking in a benzotriazole (BTA)–ethanol solution to chelate the copper and make it unreactive.
• In weaned piglets, various supplementation rates of organic Zn in the form of a chelate or as a polysaccharide complex have been evaluated and compared with ZnO, zinc oxide, at 2,000 ppm.
• The diphosphine serves as a bidentate ligand forming six-membered CPM chelate ring with a natural bite angle of 91°.
• The iminodiacetate dianion is a tridentate ligand, forming metal complexes by forming two, fused, five membered chelate rings.
• When the carboxyl group is deprotonated the glycinate ion can function as a bidentate ligand, binding the metal centre through the nitrogen and one of two carboxylate oxygen atoms, to form chelate complexes of metal ions.
• Inactive appended portions of the drug substance may include either the alcohol or acid moiety of an ester, a salt (including a salt with hydrogen or coordination bonds), or other noncovalent derivative (such as a complex, chelate, or clathrate).
• Due to the chelate effect, ligands with two phosphine groups bind more tightly to metal centers than do two monodentate phosphines.
• A particularly common subset of sigma complexes are those featuring an agostic interaction where a C–H σ-bond on one of its ligands 'leans' towards and interacts with the coordinatively unsaturated metal center to form a chelate.
