Post-Lab Questions 1. Look up the structure in your textbook of the amino acid you titrated. Write the structure you expect at pH (a) 2.5 and (b) 12 2. Compare your isoelectric point value (pl value) with the value of the amino acid listed in your textbook. How does it compare? Into which class does your amino acid fall? 3. Which data point can you obtain with greater accuracy from your graph-the pK values from the "legs" or the isoelectric...
