β¦ Synopsis
A liquid chromatographic method to analyze monosaccharides normally found in glycoprotein and glycopeptide hydrolysates is described. Monosaccharides are chromatographed as free sugars and as tritium-labeled alditols on an anion-exchange column in 0.5 M borate buffer, pH 8.6. Since the order of elution for aldoses and alditols is different, complete resolution of glucosamine, galactosamine, rhamnose, mannose, fucose, arabinose, galactose, xylose, and glucose can be obtained. Chromatography is complete in less than 1 h and the column does not require regeneration. The method was applied to the analysis of human immunoglobulin, human transfenin, and a glycopeptide from Acer pseudop/atanus cell cultures. The presence of amino acids in the hydrolysates does not interfere with analysis. * Contribution No. 80-170-J, Kansas Agricultural Experiment Station,

A rapid and sensitive procedure for the analysis of neutral and amino sugars is presented. Neutral sugars are separated after conversion to the corresponding glycamines, while the amino sugars are analyzed without modification, using an automatic amino acid analyzer and fluorometric detection.

The quantitation of glucosamine and galactosamine in biological samples can be done simply and accurately on an amino acid analyzer (l-3). However, a problem often arises from the presence of tryptophan or its degradation products or from peptides produced during the mild acid hydrolysis required fo
Methyloximes have been prepared from 2-amino-2-deoxy-D-glucose, -D-mannOSe, and -o-galactose. The acetates of these derivatives yield stable compounds which are readily separated quantitatively by gas-liquid chromatography on a number of polar phases. The above compounds along with the aldononitrile
