Definition
- Adjective:
- Relating to or characterized by chelation: Describes a substance, compound, or process that involves or exhibits chelation. Chelation is a chemical bonding process where a central metal ion is bound to a molecule (a chelating agent or ligand) at two or more points, forming a stable, ring-like structure called a chelate complex.
Usage and Examples
- Adjective:
- The chelated form of iron is often better absorbed by plants than inorganic iron salts.
- This mineral supplement contains chelated magnesium for improved bioavailability.
- The scientist studied the chelated compound's stability under various pH conditions.
Advanced Usage
- "Chelated to": Used to describe the specific binding state of a metal ion.
- In this complex, the copper ion is chelated to the EDTA molecule.
- In Biochemistry and Medicine: Often describes therapeutic agents or natural processes.
- Chelated lead is more easily excreted from the body, which is the principle behind chelation therapy.
