The electrophoretic mobility characteristics of migration of different biomolecules.

The electrophoretic mobility of migration of different biomolecules

In electrophoresis, the electrophoretic mobility determines the characteristics of migration of different biomolecules. Which of the following is not having any influence in this

(a) Stereochemistry of molecules
(b) Size of molecules
(c) Molecular weight
(d) Net charge of molecules

The correct answer is:

(a) Stereochemistry of molecules

Explanation:

In electrophoresis, the electrophoretic mobility (μ) of biomolecules determines their migration rate in an electric field. The factors influencing electrophoretic mobility include:

  1. Size of molecules → Larger molecules experience more resistance and migrate slower.
  2. Molecular weight → Directly affects size and migration speed.
  3. Net charge of molecules → Molecules with a higher net charge migrate faster towards the oppositely charged electrode.

Why Not Stereochemistry?

  • Stereochemistry (3D arrangement of atoms in a molecule) does not significantly impact electrophoretic mobility because electrophoresis primarily depends on size, charge, and shape, not molecular conformation.
  • Even if stereoisomers exist, they usually have the same charge and molecular weight, so they migrate similarly unless specific interactions (like affinity electrophoresis) are involved.

Thus, the correct answer is (a) Stereochemistry of molecules

    Ans 1 Larger molecules experience more resistance and migrate slower.
    Molecular weight → Directly affects size and migration speed.
    Net charge of molecules → Molecules with a higher net charge migrate faster towards the oppositely charged electrode
