Ionizable protons are in rapid equilibrium and so you can think of an amino acid having a relative charge between 0 and 1. Plot the relative charge of glutamate as a function of pH. Ignore the N- and C-termini and use Excel or some other program to make the plot. Note that the H-H equation is ratio of [base]/[acid] and we want relative charge. Remember that groups will be in either base or acid form, so for a population [base] + [acid] = [total].
It's not completely necessary to plot it for me, but if someone could point me in the right direction in order to figure this problem out, it would be greatly appreciated. I just need some help understanding where to start and how to go about plotting it.
