For example ... WebChelation therapy is the medical treatment for reducing the toxic effect of metals. Chelating agents are organic compounds that are capable of linking to metal ions to form less toxic species that are easily excreted from the body. Chelators bind metals and remove them from intracellular or extracellular spaces.

WebJun 15, 2024 · Chelation is the formation of a chelate. A chelate is a cyclic compound which has a central metal atom bonded to at least two other atoms. Normally, a metal ion in a solution does not remain isolated. Metal ions can link with other metal ions and form chain structures. If not, metal ions make complexes with non-metal ions or molecules. basal thumb painWebBecause a polydentate ligand is joined to the metal atom in more than one place, the resulting complex is said to be cyclic—i.e., to contain a ring of atoms.
