WebSo the 20 amino acids can be split broadly into kind of two main groups. The first group includes the nonpolar amino acids, and then the second group includes the polar ones. And the nonpolar amino acids can also be thought of as the hydrophobic, or water-fearing, amino acids. And conversely, you have the polar ones.
