From kangaroo-tail collagen you have identified a series of substituted prolines. From the titration curves you deterine the pKa's of the ionizable groups as follows: Carboxyproline (pKa's 2.0, 3.8, 10.5), Aminoproline (pKa's 1.9, 9.8, 10.0 Sulfhydrylproline (pKa's 1.9, 6.0, 9.0), Hydroxyproline (pKa's 2.0, 9.0), Methylproline (pKa's 1.8, 8.8). If these fiv Proline derivatives are dissolved in a buffer system (pH = 8.5) and an electronic field is applied, which of them will mic ate to the cathode? %3D Answers A -E A Hydroxyproline B Aminoproline C Sulfhydrylproline D Carboxyproline E Methylproline
