Chelation (/ kiːˈleɪʃən /) is a type of bonding and sequestration of metal atoms. It involves two or more separate dative covalent bonds between a ligand and a single metal atom, thereby forming a ring …

Sep 19, 2023 · 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 …

Jun 24, 2023 · Chelating agents are chemical compounds that have structures that allow two or more donor atoms (or sites) to bind to the same metal ion at the same time, resulting in the formation of …

Aug 19, 2025 · A chelating agent is a chemical compound capable of forming multiple bonds with a single metal ion, much like a crab’s claw grasps an object. These agents effectively “trap” or …

Thus, chelation may be defined as an equilibrium reaction between a metal ion and a complexing agent, characterized by the formation of more than one bond between the metal and a molecule of the …

When both nitrogens coordinate to a metal ion, a stable five-member ring is formed. The word chelating, derived from the Greek chele, “claw,” describes the pincer-like way in which such a ligand can grab a …

Jul 2, 2025 · A chelating agent, therefore, is a molecule engineered or naturally occurring to bind strongly to a metal ion, typically a transition metal or lanthanide/actinide.

Oct 15, 2025 · In medical practice, chelating agents, particularly salts of EDTA, or edetic (ethylenediaminetetraacetic) acid, are widely used for direct treatment of metal poisoning because …

Chelators, or chelating agents, can form stable, water-soluble complexes with metal ions. They achieve this by binding to the metal ions through multiple coordination sites, typically involving oxygen, …

Feb 12, 2025 · Chelation therapy treats heavy metal poisoning. It’s not FDA-approved for other conditions like heart disease or autism. You receive an injection in a healthcare provider’s office or …
