An electric current is passed though an aqueous solution of a mixture of alanine (isoelectric point 6.0),glutamic acid (3.2) and arginine (10.7) buffered at pH 6. What will happen to the three amino acids?

$\begin{array}{1 1}(a)\;\text{Glutamic acid will precipitate out}\\(b)\;\text{Arginine will migrate anode}\\(c)\;\text{Alanine will migrate towards cathode at pH 6}\\(d)\;\text{None}\end{array} $

Can you answer this question?

At pH 6 , glutamic acid is present as an anion and migrates to the anode. Alginine is present as a cation and migrates to the cathode. Alanine is a dipolar ion remains uniformly distributed in solution.
Hence (d)is the correct answer.
