Final answer:
Nonpolar amino acids are typically found in the interior of proteins, while polar and charged amino acids are found on the surface.
Step-by-step explanation:
Polar and charged amino acids tend to be found on the surface of proteins, while nonpolar amino acids are typically found in the interior. This is because nonpolar amino acids have hydrophobic properties, meaning they repel water. The hydrophobic interactions between nonpolar amino acids contribute to the three-dimensional structure of the protein.
