Mathematically, the pI for an acidic amino acid is the average of pKa 1 and pKa R (the pKa of the dissociable proton in the R group); for a basic amino acid, it is the average of pKa 2 and pKa R.here is no dissociable proton in the R group. This type of amino acid is called a âsimple amino acidâ. A simple amino acid is electrically neutral under physiological conditions. NOTE: Under this definition it is possible to have a simple amino acid which is triprotic.
