Fоr а peptide whоse sequence spells the wоrd CAR, аnswer the following questions given the pKа values below. Cysteine (C): 1.7 (a-COOH), 10.8 (a-NH3+), 8.3 (R group). Alanine (A): 2.4 (a-COOH), 9.7 (a-NH3+). Arginine (R): 2.2 (a-COOH), 9.0 (a-NH3+), 12.5 (R group). Blank #1: What is the overall charge of CAR at pH 7.0? (1 pt) Blank #2: Over what pH range(s) would CAR act as a buffer? Example of a pH range: 2.5 to 4.6. Separate ranges with commas. (2 pts) Blank #3: Calculate the isoelectric point of this peptide. (1 pt) Consider a fully protonated solution of CAR, which is then titrated with a strong base. Blank #4: How many equivalents of strong base would be necessary to fully titrate CAR? (1 pt) Blank #5: Which group would be titrated first? Say something like "the side chain or arginine" or "the alpha amino group of alanine". (1 pt) Blank #6: What is the pH of the CAR solution after you've added just 0.75 equivalents of the strong base to the original, fully protonated solution of CAR? Hint; think Henderson-Hasselbach equation. (2 pts)
