Electrophoretic separation of Amino Acids

In chemistry, a zwitterion, also called an inner salt, is a molecule that contains an equal number of positively- and negatively-charged functional groups. With amino acids, for example, in solution a chemical equilibrium will be established between the “parent“ molecule and the zwitterion. The isoelectric point of an amino acid is the point at which the amino acid has no net electrical charge. It is an important characteristic for any amino acid, because every amino acid has at least two acid–base (titratable) groups. #aminoAcids #isoelectricPoint #electrophoresis #leucine
