An electric current is passed through 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 is the fate of the three acids?
Glutamic acid migrates to anode at pH 6. Arginine is present as a cation and migrates to the cathode. Alanine in a dipolar ion remains uniformly distributed in solution
Glutamic acid migrates to cathode and others remain uniformly distributed in solution.
All three remain uniformly distributed in solution.
All three move to cathode
In aqueous solution glucose remains as
only in open chain form
only in pyranose form
only in furanose form
n all three forms in equilbrium
