WebThe charge is largely determined by the side chains. For the case of lysine at physiological pH, the N-terminus is protonated (+1), the C-terminus is deprotonated (-1), and the side chain amino group is protonated (+1). It will have a positive (+1) net charge. WebThe pI for lysine is simply the average of the pK a 's of the two -NH 3 + groups. pI = 9.18 + 10.79 10.0 2 . At this pH, all of the carboxylic acid groups are present as -CO 2-ions and …

However, the pKa of the side chains of arginine or lysine is around pH 10–12, which is inconsistent with the pH … WebThus, at pH 7.0, one finds that the net charge of the hypothetical peptide is -2.0. It has been shown by Tanford and coworkers 2"3 that the hydrogen ion titration curves of proteins can be com- pletely predicted from the unperturbed pKa values of the ionizable groups when the interactions (eg, electrostatic, ...
