Binding interactions can be classified into several types based on the nature of the interaction:
Covalent Binding: This involves the formation of stable, often irreversible, chemical bonds. An example is the binding of alkylating agents to DNA, leading to mutations. Non-covalent Binding: Includes hydrogen bonds, ionic bonds, van der Waals forces, and hydrophobic interactions. These are typically reversible and play a role in receptor-ligand interactions.
