Determination of D - and ~ Amino Acids by Ion Exchange
A procedure for the precise determination of the D and L isomers in a given sample of an amino acid has been based upon chromatographic separation of the diastereoisomeric dipeptides obtained by derivatization with an L-amino acid N-carboxyanhydride. The conditions for the preparation of dipeptides developed by Hirschmann and associates make the derivatization step simple and rapid; the couplin...
متن کاملNotes on the determination of amino acids by ion-exchange chromatography.
Dowex 50. The resin, kindly supplied by Dow Chemical International Ltd., Midland, Michigan, U.S.A., was stated to be of nominal 12% cross-linking and 200-400 mesh. Sodium phosphate buffer pH 6-8, 0.1M. This buffer was adjusted to pH 6-75 in order to delay slightly the emergence of the histidine peak. At the lower pH, histidine emerges separated from and almost mid-way between hydroxylysine and ...
متن کاملPreparative Isolation of Amino Acids by Carrier Displacement Chromatography on Ion Exchange Resins* by Donald
Chromatographic separations of amino acids on ion exchange resins may be performed on a preparative scale either by elution (24) or by displacement (5-12). Some of the exceptional resolving power demonstrated in analytical separations by elution techniques (13, 14) disappears when larger columns with relatively higher loads are used (2). Displacement chromatography allows large quantities of so...
