A scientist examines a supermolecule model in the laboratory.

Definition

1. Noun:
   • A very large, complex molecule: A supermolecule is an extremely large and intricate molecule, typically formed from the association of smaller molecules. These structures are often found in biological systems within plants and animals.

Examples of Usage

• Noun:
  • DNA is considered a supermolecule due to its immense size and complex double-helix structure.
  • Scientists are studying the protein assembly to understand how it functions as a single supermolecule.

Advanced Usage

• In Supramolecular Chemistry: The term "supermolecule" is often used in the field of supramolecular chemistry to describe a complex of molecules held together by non-covalent bonds (like hydrogen bonds or van der Waals forces) rather than covalent bonds.
  • The research focused on the self-assembly of a cage-like supermolecule from smaller organic units.

Variants and Related Words

• Supramolecular (adj): Relating to or denoting structures composed of molecules held together by non-covalent forces.
  • Supramolecular chemistry explores the properties of these non-covalent assemblies.
• Macromolecule (n): A molecule containing a very large number of atoms, such as a polymer or protein. While similar, "macromolecule" often implies a single, large covalent polymer, whereas "supermolecule" can imply an assembly of distinct molecules.
  • Cellulose is a natural macromolecule.

Synonyms

• Supramolecular assembly: A complex structure formed from molecular components.
• Molecular complex: An association of molecules.

Related Phrases

• Form a supermolecule: To associate into a large, complex structure.
  • Under the right conditions, these peptides will form a stable supermolecule.
