Amino acids comprising a polypeptide with high isoelectric point (p I ). Introduction: p I of the amino acid is the state where the amino acid carries no charge; means, amino acid is electrically neutral. The isoelectric point of an amino acid can change with a change in pH. If the concentrationofhydronium ( H + ) ions is lowered in a solution, the amino acid loses all its protons and becomes negatively charged. The amino acid gains a positive charge when it gains protons in the presence of high pH.
