chelate
(gcide) | chelate \che"late\, n. (Chem.)
a compound formed by combination of a metal ion in solution
with a compound containing heteroatoms (such as oxygen or
nitrogen), in which at least two heteroatoms are bound to the
metal. The bonds may be covalent or non-covalent. Chelates in
some cases have very low dissociation constants, and organic
compounds (chelating agents) which form such chelates are
therefore used to reduce the concentration of free metal ions
in solution.
