THIRD PROBLEM SET 1. We generally write the structure of the amino acid lysine as found in a cell as: COO - + NH 3 -C-CH 2 -CH 2 -CH 2 -CH 2 -NH 3 + H In text books, it is often written as: COOH NH 2 -C-CH 2 -CH 2 -CH 2 -CH 2 -NH 2 H a. Circle the groups in the above two structures that are likely to act as acids. Explain your reasoning. b. Put a triangle around the groups in the above two structures that are likely to act as bases. Explain your reasoning. c. Draw the structure of this amino acid as it would appear at very high pH, at very low pH. Explain your reasoning. d. Why does chymotrypsin become inactive at high pH. 2. Circle ALL the correct answers in each of parts a, b and c. After the reaction A B has reached equilibrium: a. the rate at which A is converted to B is constant , increasing , decreasing , zero . b. the concentration of A is constant , increasing , decreasing, zero , dependent on the Δ G of the reaction . c. the rate at which A is converted to B is greater than
