Consider the following tetrapeptide, at pH = 6:
(N-term) - Ser - Glu - Cys - Arg - (C-term)
i) (3 pts) For which amino acid side chain in the peptide is the fraction dissociated the highest, at pH = 6? Explain briefly how you arrived at your answer.
ii) (5 pts) Estimate the net charge (to the nearest integer) on the peptide at pH = 6. Explain briefly how you arrived at your answer. Be sure to consider the amino acid side chains and the amino- and carboxy-termini (N-term and C-term)!
