    1) Which of these amino acids have polar side chains?

    The side chains on the amino acids do no include the NH3 on the left or the COO on the right. For an amino acid to have a polar side chain, it must contain a polar functional group such as a carbonyl (C=O). Leucine and alanine only contain ...

    Solution Summary

    This solution explains how to determine:

    1) If amino acids have polar side chains.

    2) If amino acids have side chains that can form hydrogen bonds.

    3) If amino acids can form a salt bridge.
