Chelation (/ kiːˈleɪʃən /) is a type of bonding of ions and their molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a polydentate (multiple bonded) ligand and a single central metal atom. [1][2] These ligands are called chelants, chelators, chelating agents, or sequestering agents.

2023年9月20日 · Chelation therapy uses special drugs that bind to metals in your blood. You get the chelating medicine through an intravenous (IV) tube in your arm. It’s also available in pill form. Once the...

2023年7月30日 · Chelating agents are ligands that are able to form two or more coordinate covalent bonds with a metal ion. An important and interesting example of this is the chelating agents—ligands which are …

2023年6月24日 · Chelating agents control metal ions by inhibiting the metal ion reactive sites and preventing them from entering their regular reactions.

Chelating agents control metal ions by blocking the reactive sites of the metal ion and preventing them from entering into their normal (and in many cases undesirable) reactions.

2019年7月3日 · Chelation, according to the IUPAC, involves the formation of two or more separate coordinate bonds between the ligand and central atom. The ligands are terms of chelating agents, chelants, chelators, or sequestering agents. Chelation therapy is used to remove toxic metals, as in heavy metal poisoning.

2023年6月30日 · A metal ion in solution does not exist in isolation, but in combination with ligands (such as solvent molecules or simple ions) or chelating groups, giving rise to complex ions or coordination compounds.
