The term "supermolecule" refers to a large molecule composed of smaller molecules that are held together by noncovalent interactions. Synonyms for supermolecule include macromolecule, polymer, oligomer, and supramolecule. Macromolecule refers to a large molecule made up of smaller units, such as proteins, nucleic acids, and carbohydrates. A polymer is a long-chain molecule consisting of many identical or similar subunits, such as plastics and synthetic fibers. An oligomer is a molecule consisting of a few monomers, while a supramolecule is a large molecular structure formed by noncovalent interactions between smaller molecules. All these terms are used to describe large, complex molecules that play a vital role in various biological and chemical processes.
