Question
Compare the following amino acids and answer the following prompts:
L
CH₂
CH
H₂N
COO
H₂N
CH₂
COO™®
a) What groups do these amino acids belong to (polar, basic, acid, hydrophobic or aromatic)?
b) Which amino acid has a net charge of -1 at pH= 8?
c) If you made a dipeptide by forming a peptide bond between these two, what would be the net
charge on the dipeptide at pH = 7?
d) If the amino acid on the right was substituted for the one on the left in a protein, what effect do
you predict would occur?
e) Which residue would you most likely find on the interior of a water-soluble protein?
