Molecualr level understanding of molecular recognition, catalysis, chemical transport, etc., warrants how non-covalent interactions are manifested and modulated during these processes. Further, non-covalent interactions also impart and control the three dimensional structure of macromolecules and the way in which folding, aggregation and change from one state to another state. The concept of cooperativity among non-covalent interactions is defined and discussed. Importantly how the cooperative manifests itself in molecular aggregation will be dealt with in a quantitative fashion. Illustrative examples are taken which highlight the characteristic nature of non-covalent interactions and their sharp contrast with the way in which covalent interactions manifest.
