Choose the correct statement about isoelectric point
Amino acid at low pH, placed in electric field migrate towards anode.
At this point amino acid is present in the form of Zwitter ion
Amino acid at high pH, placed in electric field migrate towards cathode.
At this point amino acids are basic in nature
At isoelectric point, the concentration of zwitter ion is maximum.
Isoelectric point is pH in which amino acid shows no migration towards any electrode.
At isoelectric point net charge of amino acid is zero.
