Aspartic acid has 3 ionizable functional groups. (Use the pKa values found in the book) a). Draw the titration curve of aspartic acid b) Draw the structures of the predominant ionization state of aspartic acid at pH1,5, 8 , and 12. (c) What is the net charge of aspartic at pH1,5,8, and 12 ? (d) For each pH, will aspartic migrate toward the anode (+) or cathode () when placed in an electric field? (e) Calculate the isoelectric point (PI) for aspartic acid
