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.
The 4 main macromolecules in cells made largely from C, O, H, and N are Carbohydrates, Lipids, Proteins, and Nucleic Acids. For each of these 4 macromolecules, I would like you to know: 1. What the monomer (basic building block) is 2. What types of polymers result 3.
