Consider a free lysine amino acid in a solution buffered to pH = 9.00. What will be the overall charge on the residue?
Is it -2, -1, 0, 1, 2?

The overall charge on the residue ( lysine residue ) is ; ( C )  0 charge

The a-aminium group of lysine amino acid will begin deprotonating by the presence of NaOH as the pH level of the solution increases.

Given that the pKa level of a-aminium group = 9. when the pH of  the solution is buffered to 9.0 . half of the a-aminium ions that is present in the lysine amino acid will deprotonate leaving the overall charge on the lysine residue at neutral ( 0 charge ).

Hence we can conclude that the overall charge on the residue is a 0 charge.
