Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Amino acids exist as Zwitter ions which contain both positive and negative charge but overall electrically neutral. At their isoelectric point, amino acids do not migrate to any electrode and remain uniformly distributed in the solution. Thus, alanine (isoelectric point 6.0) does not move to any electrode. At a pH lower than their isoelectric point, they exist as cation and move towards the cathode. Thus, arginine (isoelectric point 10.7) exits as a cation. At a pH higher than their isoelectric point they exist an anion and move towards the anode. Thus, glutamic acid (isoelectric point 3.2) at pH 6.0 moves towards the anode. video solution - https://youtu.be/YXH1lKVCFo0
