Quizplus · Accepted Answer

Amino acids have different functional groups that can be hydrophobic or hydrophilic. Some examples include the hydrophobic side chains of alanine and valine, and the hydrophilic side chains of aspartic acid and lysine. The functional groups are not always charged, and they are not identical in all amino acids. Additionally, amino acid functional groups may contain nitrogen in addition to carbon, hydrogen, and oxygen.
