Towards which electrode will an amino acid move whose `pH gt pl` ?

Predict towards which electrode would an alpha - amino acid migrate in an electric field at a pH > pI. Explain.

Predict towards which electrode would an alpha - amino acid migrate in an electric field at a pH = pI. Explain.

What is isoelectric point? Isoelectric point of a protein is 6.0. If the pH of the protein sol is 8, then towards which electrode will the protein particles move during the process of electrophoresis?

(A) : In electric field, an amino acid migrate towards cathode when pH gt pI (R ) : When pH is greater than PI anionic form of amino acid predominates.

The isoelectric point(pl) of an amino acid is the pH of wihc it has no net charge. The pl of an amino acid that does not have an ionizable side chain such as alanine, is midway between its two pka values. If an amino acid has ionizable side chain. its pl is the average of the pka values of the similarly ionizing groups. Find the structure of the following amino acids at pH=1:
