"Webb27 aug. 2024 · Titration Curve of Lysine. At very acidic pH, the R- group is in the – NH 3 + form, the alpha-amino group is in the – NH 3 + form and the alpha-carboxyl group is in the COOH form so the lysine has a net charge of +2. As we titrate with hydroxide ion, we remove hydrogen ions. They combine with hydroxide ions and become water. " - Pi on titration curve
