Show the approximate position of the indicated four amino acids following electrophoresis. Here you have to consider both the polarity and the value of the total net charge of the amino acid. Assume that an amino acid with a net charge of +2 will migrate twice as far towards the minus pole as an amino acid with a net charge of +1. To provide some guidance on how to indicate the amino acids, we show in the image the migration of an example amino acid with unknown net charge; you do not have to consider its migration behaviour in your decision to place the four amino acids.

To provide some guidance on how to indicate the amino acids, we show in the image the migration of an example amino acid with unknown net charge; you do not have to consider its migration behaviour in your decision to place the four amino acids.

Follow-up Question

Provide for each amino acid the names that will uniquely identify all ionisable groups and indicate
individual charges associated with these groups and the overall charge of the amino acid.
