This question concerns the tetrapeptide His-Leu-Lys-Ser, that you drew in the previous question. You are advised to work this out on paper first and then transfer you answers to the pulldown menus (5 pts, 0.5 each) The relevant pKa values for the His-Leu-Lys-Ser tetrapeptide are 3.5, 6.5, 8, and 11. For this peptide, choose the group or side chain from the pulldown menu that most likely matches each pKa value given below. pKa Group/Sidechain 3.5 6.5 8 11 3.5 6.5 [Select] 7 [Select] Calculate the overall charge of the peptide at the five different pH values given on the left. In the pull down menu, choose the correct overall peptide charge at that pH pH Charge [Select] [Select] [Select] [Select] [Select]
