Statement I: At isoelectric point of alanine (pI = 6.01), it moves towards cathode Statement II: At isoelectric point the solution of amino acid is neutral |
Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I Both Statement I and Statement II are correct and Statement II is not the correct explanation of Statement I Statement I is correct but Statement II is false Statement I is false but Statement II is correct |
Statement I is false but Statement II is correct |
The correct answer is (4) Statement I is false but Statement II is correct. Statement I: At the isoelectric point of alanine (pI = 6.01), it moves toward the cathode. This statement is false. At the isoelectric point, the amino acid is neutral and has no net charge. Therefore, it will not move towards either the anode or the cathode in an electric field. Statement II: At the isoelectric point the solution of amino acid is neutral. This statement is correct. At the isoelectric point, the amino acid is in its Zwitter ionic form, which means that it has both a positive and a negative charge that cancel each other out. Therefore, the correct answer is Statement I is false but Statement II is correct. |
