Introduction to Comparing Biological Macromolecules

Discuss biological macromolecules and the differences between the four classes

As we’ve learned, there are four major classes of biological macromolecules:

  • Proteins (polymers of amino acids)
  • Carbohydrates (polymers of sugars)
  • Lipids (polymers of lipid monomers)
  • Nucleic acids (DNA and RNA; polymers of nucleotides)

Let’s take a closer look at the differences between the difference classes.
