Macromolecule. Definition. noun, plural: macromolecules. A large complex molecule, such as nucleic acids, proteins, carbohydrates, and lipids, with relatively large molecular weight.Supplement. In biology, a macromolecule is a term used to contrast a micromolecule (which is smaller in size and in molecular weight).Macromolecules are usually used to refer to large biological polymers, such as nucleic acids and proteins, which are made up of small monomers linked together.upplement.

1 Within cells, small organic molecules are joined together to form larger molecules. 2  These large macromolecules may consist of thousands of covalently bonded atoms and weigh more than 100,000 daltons.  The four major classes of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
