Electrophoresis is the movement of molecules within a matrix (paper, gel) to which an electric field is applied – from a central origin, a molecule with a net positive charge

Electrophoresis is the movement of molecules within a matrix (paper, gel) to which an electric field is applied – from a central origin, a molecule with a net positive charge moves toward the negative pole (often called cathode) and a molecule with a net negative charge moves toward the positive pole (often called anode). for the pentapeptide: N – Lys  –  gly  –  asp  –  his  –  glu  – C is the net charge at pH 3? 2. is the net charge at pH 11? 3. At pH 3 will the pentapeptide move to the negative pole,      positive pole or not move? 4. At pH 11, the same question.
