Below are pKa values for common amino acids.  Below are some postulated ionic species for a dipeptide. Blank #1: Use 3-letter abbreviations to name this dipeptide.  Blank #2: Which are the ionic species that are possible for this dipeptide at any given pH? List them by the letters identifying each ionic species (for example: A, B, C) Blank #3: Identify the zwitterion by the corresponding letter (for example: A) Blank #4: In which pH range does >90% of the -1 ion exist? (for example: 1.1 to 3.1) Blank #5: What is the isoelectric point of this dipeptide?
