Influence of the Length of the Alanine Spacer on the Acidic–Basic Properties of the Ac–Lys–(Ala)(n)–Lys–NH(2) Peptides (n = 0, 1, 2, …, 5)

By using the potentiometric titration method, we have determined the pK (a) values of the two terminal lysine groups in six alanine-based peptides differing in the length of the alanine chain: Ac–Lys–Lys–NH(2) (KK), Ac–Lys–Ala–Lys–NH(2) (KAK), Ac–Lys–Ala–Ala–Lys–NH(2) (KAK2), Ac–Lys–Ala–Ala–Ala–Lys–...
