Mannopyranosyl Uronic Acid Donor Reactivity
Organic Letters, 2011The reactivity of a variety of mannopyranosyl uronic acid donors was assessed in a set of competition experiments, in which two (S)-tolyl mannosyl donors were made to compete for a limited amount of promoter (NIS/TfOH). These experiments revealed that the reactivity of mannuronic acid donors is significantly higher than expected based on the electron ...

Automated ion-exchange chromatography of uronic acids and uronic acid containing oligosaccharides
Analytical Biochemistry, 1968Abstract An automated anion-exchange chromatographic procedure for the separation of uronic acids and uronic acid containing oligosaccharides is described. The method has been applied, in particular, to the separation and quantitation of l -iduronic and d -glucuronic acid in hydrolyzates of dermatan sulfate, and the hydrolysis conditions required ...

A modified uronic acid carbazole reaction
Analytical Biochemistry, 1962Abstract A modification of Dische's carbazole reaction for uronic acid in the presence of borate is described. The advantages of the procedure are: 1. (1) There is an approximately twofold increase of sensitivity. The OD is a linear function of concentration between 4 and 40 μg/ml. 2. (2) Maximum color develops immediately. 3.

Abstract Starting from the anomers of methyl (methyl D -galactopyranosid)uronate the corresponding Δ 4,5 unsaturated uronic acid derivatives, the anomeric methyl (methyl 4-deoxy- L - threo -hex-4-enopyranosid)uronates, have been prepared by a base-catalyzed elimination reaction.

Identification of uronic acids in mucopolysaccharides
Archives of Biochemistry and Biophysics, 1963The isolation or identification of uronic acids from acid mucopolysaccharides can be achieved by hydrolysis with formic acid and chromatography of the hydrolyzates.

Synthesis and Application of Uronic Acids
Current Organic Chemistry, 2014This review concerns selected methods for the synthesis of uronic acids and uronic acid-containing oligosaccharides. Construction of uronic acids is broadly represented by methods based on carbohydrates and non-carbohydrates as well as de novo synthesis.

Analytical Biochemistry, 1963
Abstract A method is presented for the rapid differentiation, on a micro scale, of glucosamine, galactosamine, glucosamine uronic acid, and galactosamine uronic acid by paper electrophoresis of their deamination products in borate buffer. A new spray reagent for the specific detection of the 2-amino-2-deoxy sugars is also described; this is based on ...

Studies on uronic acid materials
Carbohydrate Research, 1968Abstract Some of the analytical parameters for Acacia senegal gum have been determined for ( a ) twelve “bulk” samples of tapped gum from three different districts of the Sudan, and ( b ) thirteen, different, single-nodule specimens of “natural exudate” gum.

Modification of polysaccharides containing uronic acid Residues
Carbohydrate Research, 1975Klebsiella Type 47 capsular polysaccharide has side chains attached to the main chain via D-glucuronic acid residues. The side chains have been removed to yield an essentially linear polysaccharide by the following sequence of reactions: (1) substitution of hydroxyl and carboxyl groups with methyl vinyl ether; (2) beta-elimination by treatment with ...

Uronic Acids in Oligosaccharide Synthesis
European Journal of Organic Chemistry, 2007AbstractThis Microreview covers some general strategies for the preparation of uronic acid residues and their incorporation into anionically charged oligosaccharides. Two distinct strategies can be recognized: (1) glycosylation followed by oxidation, and (2) oxidation of the monosaccharide building blocks followed by glycosylation.
