Draw the ionized form for each of the following amino acids. Arginine, Tyrosine
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.
