The repeating structural unit of most simple polymers not only reflects the monomer(s) from which the polymers are constructed, but also provides a concise means for drawing structures to represent these macromolecules. For polyethylene, arguably the simplest polymer, this is demonstrated by the following equation.
By Anne Marie Helmenstine, Ph.D. Definition: A macromolecule is a molecule with a very large number of atoms. Macromolecules typically have more than 100 component atoms. Examples: Most polymers are macromolecules and many biochemical molecules are macromolecules.Proteins, DNA, RNA and plastics are all macromolecules.efinition: A macromolecule is a molecule with a very large number of atoms.
