1. Using the amino acid chart on the back of this worksheet, divide the amino acids into the following groups:
hydrophobic, hydrogen bonding, acidic, basic, amide, small, able to form sulfide bonds. List the symbol for the
amino acids in the space provided. Use the third row of the chart to indicate the role the amino acids in this
group will play in the structure of the protein or other special features. Not all amino acids will be used.
hydrophobic
