5) For each of the amino acids in problem 3, indicate the ionic form which predominates at the pH values below. Calculate the isoelectric point for each amino acid. pka for lysine: 2.2 (α-COOH); 9.0 (α-NH³¹); 10.5 (R group) pka for cysteine: 1.7 (a-COOH); 10.8 (a-NH3¹); 8.3 (R group) pka for glutamate: 2.2 (α-COOH); 9.7 (a-NH3); 4.3 (R group) a) pH = 1.0 b) pH = 7.0 c) pH = 13
