Electrophoretic mobility and dissociation constants of tripeptides evaluated by isotachophoresis
1Faculty of Engineering, Hiroshima University, Japan.
Ionic mobilities and dissociation constants of twenty peptides (seventeen tripeptides and a few oligoglycines) were evaluated on the basis of the observed isotachophoretic qualitative indices RE in the pH range 8.1-9.5 by the use of a least-squares method. Good correlation was obtained among the mobilities of amino acids, dipeptides and tripeptides when the clay ball model and the conventional formula weight were adopted.
