The chelate effect is a phenomenon in coordination chemistry where a ligand forms a more stable complex with a metal ion when it binds to the metal ion through multiple points of attachment, rather than just one. This increased stability is due to the formation of a ring structure, known as a chelate ring, which effectively "locks" the metal ion in place and prevents it from interacting with other molecules. The chelate effect is commonly observed in biological systems, where it plays a crucial role in various processes such as enzyme catalysis and metal ion transport.

The chelate effect is the enhanced stability of a coordination complex due to the presence of a chelating ligand. Chelating ligands are ligands that can bind to a metal ion through more than one coordinating group. This results in the formation of a ring structure, which increases the stability of the complex. The chelate effect is observed because the chelating ligand forms multiple bonds with the metal ion, which results in a decrease in the entropy of the system. This decrease in entropy is compensated for by an increase in the enthalpy of the system, which results in a more stable complex.

The chelate effect is important in a variety of biological processes, such as the binding of metal ions to proteins and the transport of metal ions across cell membranes.
