The building blocks for proteins are amino acids, all of which have the same basic chemical pattern. They differ by their “R groups” (also called “side chains”)

The 20 amino acids found in proteins can be subdivided into two groups… Hydrophobic Hydrophilic When the protein folds into its 3D shape, the hydrophillic AA’s tend to be exposed at the surface while the hydrophobic AA’s tend to be buried in the interior.
