What is a main function of supramolecular complexes?

Supramolecular complexes play a critical role in biological systems through molecular recognition and temporary association. This aspect is vital for numerous biochemical processes, such as enzyme-substrate interactions, receptor-ligand binding, and the formation of cellular structures. These complexes can assemble and disassemble easily, allowing for dynamic interactions essential for cellular communication and metabolic pathways.

This temporary nature of associations enables supramolecular complexes to facilitate processes such as signal transduction, where molecules like hormones bind to receptors and trigger a response within the cell without forming permanent bonds. Such transient interactions are crucial for maintaining the flexibility and adaptability of biological systems, allowing them to respond to changes in their environment.

Other functions listed do not capture this essence of temporary associations inherent to supramolecular complexes, emphasizing their ability to form and break bonds as needed in a living organism. This functionality is what truly defines and differentiates supramolecular complexes from more stable, permanent macromolecule interactions.
