Problem regarding the isoelectric point

Reference no: EM131019876

An amino acid has three ionizable groups, the α-amino and α-carbonyl groups and a side chain that can be positively charged. The p^Kvalues are 7, 3, and 11, respectively. Which of the following p^H values is nearest to the isoelectric point (the point at which the overall net charge is zero) for this amino acid: 1.1, 5.3, 12.2? Explain your answer.
