Histidine is an amino acid with three titratable groups: an -NH3+ group (pKa = 9.2), a -COOH group (pKa = 1.8), and an imidazole (amine-like) group (pKa = 6.0). The titration curve for histidine is shown below with four points highlighted. (a) Identify which point on the titration curve corresponds to the pKa for each of the titratable groups, and which point corresponds to the pI. Explain your choices. (b) Calculate the value of pI for histidine
Draw the titration curves for the following AA’s: Aspartic acid, Alanine, Lysine, Valine, Serine, and Trrosine.
LEFT:You have the following titration curve of an amino acid with a non-polar R-group with
arrows on curve from (1) to (5).
RIGHT: This amino acid has the following structures (a) to (e)) at different points of the
titration curve. Match each numbered arrow on the curve (from (1) to (5)) with the appropriate
