SOLVED: Draw the titration curve for the titration of 20 mL of a 0.15 M solution of the peptide, NHYF (carboxylic acid pKa = 2.0, amino pKa = 8.0, use only the pKa for the R groups in our text, use pages 155, 157, and 160) with 0.10 M sodium hydroxide. Clearly label the axes of your graph (pH vs mL of NaOH added). Be sure to include pH values and volumes for the following: Start of the titration (no sodium hydroxide added), the pH at the volume that is half of the volume of each endpoint, pH and

SOLVED: All amino acids have two ionizable functional groups: an Î±-amino group (average pKa of 9.4) and an Î±-carboxylic acid group (average pKa of 2.2). Cysteine has an ionizable side chain (R group) with a pKa of about 8.3. At what pH would the structure be the predominant ionization state? Consider the ionization state of all three of the functional groups. (4.8, 8.9, 8.3, 11.9, 1.5, or 7.0)The protonated form of the R group of cysteine is shown in the structure. The ratio of the protonated

SOLVED: Next, analyze Lysine, which contains an amine in the side chain. The pKa of the amine is 8.95, while the pKa of the carboxylic acid is 2.18 and the pKa of the amine in the side chain is 10.53. Identify the pH that would give the predominant ionization state for each structure.Structure A predominates at pKa . Structure B predominates at pKa . Structure C predominates at pKa .
