Chloride bridges in proteins

Chloride bridges in proteins are interactions where chloride ions (Cl−) connect different parts of a protein molecule. These ions can stabilize the protein’s structure by forming electrostatic links between amino acid residues, especially in ionic or polar regions. Essentially, chloride ions help maintain the protein’s shape by acting as molecular connectors, contributing to its overall stability and proper function. This stabilization is important in environments where chloride ions are abundant, such as within cells or biological fluids.
