There are basically three major classifications for amino acids (1) those with nonpolar R group, (2) those with uncharged polar R groups, and (3) those with charged polar R group. The table below shows us all 20 amino acids with their codes.
About 9 amino acids have non-polar R-groups and are relatively hydrophobic. Another 6 amino acids have strongly polar R-groups which readily attract water molecules. These are hydrophilic amino acids. The remainder, about 5 amino acids, have R-groups which can ionize. At normal cellular pH's these R-groups become electrically charged, making them even more hydrophilic than the polar amino acids. Any of the 20 different amino acids can occur in any position along a polypeptide chain.
