    What is isoelectric point of amino acid? How does it help in the separation of amino acids?

    Answer:

                         The pH at which a particular amino acid does not migrate under the influence of an electric field is called isoelectric point of amino acid. For example, isoelectric point of glycine is 6.1. At the isoelectric point, an amino acid does not dissolve in water. This property helps in the separation of different amino acids formed by the hydrolysis of proteins.
