molekyylikompleksi

Molekyylikompleksi is a Finnish term that translates to molecular complex in English. It refers to a chemical species formed by the association of two or more molecules, ions, or atoms held together by non-covalent interactions. These interactions can include hydrogen bonds, van der Waals forces, dipole-dipole interactions, and pi-pi stacking. Unlike covalent bonds, these forces are weaker and reversible.

Molecular complexes are prevalent in various scientific disciplines, including chemistry, biology, and materials science. In biological systems, they are fundamental to many processes. For instance, enzyme-substrate interactions, where an enzyme binds to its substrate, are often mediated by molecular complex formation. Similarly, DNA and RNA structure relies on the formation of hydrogen bonds between base pairs, creating stable molecular complexes. The binding of drugs to their target molecules within the body also typically involves the formation of temporary molecular complexes.

In chemistry, molecular complexes are studied to understand intermolecular forces and to design new materials. Supramolecular chemistry, a field closely related to molecular complexes, focuses on the study of organized structures formed by the association of molecules. These complexes can exhibit unique properties not found in their individual components, leading to applications in areas like drug delivery, catalysis, and sensing. The strength and stability of a molecular complex depend on the nature of the interacting species and the specific non-covalent forces involved.
