Homework Answers
1) Amino acids used in proteins are generally L-amino acids.
2) Polar R groups , along with acidic and basic R groups are said to be Hydrophilic because these are attracted to water molecules.
3) 
this represent zwitter
ion.

Draw the ionized form for each of the following amino acids lysine proline V Tyr Classify each of the amino acids in problem 16.5 as polar or nonpolar. If polar, indicate if the R group is neutral acidic, or basic. Indicate if each is hydrophobic or hydrophilic. Classify each of the amino acids in problem 16.6 as polar or nonpolar. If polar, indicate if the R group is neutral, acidic, or basic. Indicate if each is hydrophobic or hydrophilic.
