When polydentate ligands bond with the central atom and form an organic compound is called chelate. There are so many examples of chelates. It is a heterocyclic compound which reacts to form a chelate and form a ring by forming one or more hydrogen bonds. It works by binding metal in the bloodstream.

Complete step by step answer:
Chelate, any of a class of coordination or complex compounds consisting of a central metal atom attached to a large molecule, called a ligand, in a cyclic or ring structure.
There are so many examples of chelate. Here we try to understand about chelates with example:

Ethylene diamine ligand has two points of attachment to the cadmium ion, thus forming a ring; it is known as a bidentate ligand. Ligands that can attach to the same metal ion at two or more points are known as polydentate ligands.
Importance of chelate:
1.It attaches minerals to other substances, such as organic in order to increase their bioavailability.
2.It is useful for softening hard water.
3.It is used in separation of lanthanides and actinides.
4.It is based upon the target heavy metal like iron, copper, mercury and lead being the major targets.
5.It is useful for providing nutritional supplements.

Note:Chelate any class of complex compounds consisting of ligands and metal atoms and form a chelate ring. Chelates are stable complexes of metal ions with organic substance as a result of ring shaped bonds. The stability is a result of the bond between the chelator, which has more than one pair of free electrons, and the central metal ion.
