Question: amino acids are weak polyprotic acids containing at least two...

Question details

Amino acids are weak polyprotic acids containing at least two dissociable protons (from COOFH and NHs groups). Illustrate the titration of a) glycine, b) glutamic acid, and c) lysine with the help of appropriate titration curves. Your answer must contain the pK values for the associated and dissociated forms for each of the three amino acids. Determine the isoelectric point (zD for each amino acid?
