At a particular pH, the amino acid glutamic acid has a net charge of zero. When this pH is achieved, it is said to be at glutamic acid's:
|A|| Isobaric point|
|B|| Isomeric point|
|C|| Isotonic point|
|D|| Isoelectric point|
Ans. D At a certain pH (unique for each amino acid), the net charge of an amino acid equals zero. When this pH is achieved, it is said to be at the amino acid's isoelectric point. At the isoelectric pH of an amino acid, the net movement of that particular amino acid will be zero when the amino acid is subjected to an electric field.
