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.
CH 5. Structure & Function of Large Molecules: Macromolecules. Molecules of Life. All living things are made up of four classes of large biological molecules: carbohydrates, lipids, proteins, and nucleic acids. Macromolecules are large molecules composed of thousands of covalently connected atoms. Molecular structure and function are inseparable. Macromolecules: Polymers built from Monomers A polymer is a long molecule consisting of many similar building blocks. These small building-block molecules are called monomers. Three of the four classes of lifeâs organic molecules are polymers: Carbohydrates Proteins Nucleic acids Synthesis & Breakdown of Polymers A dehydration reaction occurs when two monomers bond together through the loss of a water molecule.
