5. Which amino acid listed in the pKa table may behave as a zwitterion at a pH of 7.0-7.4?
Consider the partial sequence of a peptide.I L W A N R M S H V L F A V E ASelect all amino acid residues likely to be on the solvent‑exposed surface once the peptide folds into its native conformation.
The isoelectric point (pl) can best be calculated by: Averaging the sums of all pkas. Averaging the sum of the two pKas closest to physiological pH. Averaging the two pKas "sandwiching" the zwitterionic form. Averaging the two pKas of the alpha-amino and alpha-carboxy groups.
