Salt bridges are non-covalent interactions that occur between oppositely charged residues in proteins, playing a crucial role in stabilizing protein structures and influencing protein folding and function. They are particularly important in maintaining the integrity of tertiary and quaternary structures, especially under physiological conditions where they contribute to the overall electrostatic interactions within the biomolecule.

Non-covalent interactions are critical forces that stabilize the three-dimensional structures of biomolecules and mediate interactions between them, without involving the sharing of electron pairs. These interactions, such as hydrogen bonding, ionic interactions, and van der Waals forces, are generally weaker than covalent bonds but are essential for the dynamic and reversible nature of biological processes.

Proteins are essential biomolecules that perform a wide array of functions in biological systems, including catalyzing biochemical reactions, providing structural support, and regulating cellular processes. Their function is determined by their three-dimensional structure, which is encoded by the sequence of amino acids and influenced by the cellular environment.

Physiological conditions refer to the normal functioning states of an organism's body systems, which can be influenced by various factors such as genetics, environment, and lifestyle. Understanding these conditions is crucial for identifying deviations that may indicate disease or abnormal health states.
