Chelated
Chelated
Chelated (pronounced: /kɪˈleɪtɪd/) is a term used in Chemistry and Medicine to describe a specific type of chemical reaction. The term originates from the Greek word "chēlē", which means claw, referring to the way a chelating agent grabs onto a metal ion.
Definition
In chemistry, a chelated compound is one in which a central metal ion is bonded to a large molecule in a cyclic or ring structure. In medicine, chelated refers to a process by which minerals are combined with amino acids or other molecules to improve their absorption by the body.
Usage in Medicine
In the field of medicine, chelated compounds are often used in treatments for heavy metal poisoning. The chelating agent binds to the toxic metal, forming a stable, water-soluble complex that can be excreted from the body. This process is known as Chelation Therapy.
