The Collaborative International Dictionary of English v.0.48 (gcide)

Chelate \Che"late\, a. (Zool.)
Same as {Cheliferous}.
[1913 Webster]

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.
[PJC]
