Synthesis and Application of Uronic Acids

Current Organic Chemistry, 2014
This 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.

Detection and rapid differentiation of glucosamine, galactosamine, glucosamine uronic acid, and galactosamine uronic acid

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, 1968
Abstract 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, 1975
Klebsiella 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, 2007
AbstractThis 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.

Stereoselective glycosidations of uronic acids

Tetrahedron Letters, 1980
Abstract Stereoselective glycosidation and disaccharide formation of uronic acids were performed with silver perchlorate in acetonitrile. The course of the reaction is controlled by intermediate nitrilium acetonitrile conjugates, which are generated in situ.

Aldonic and Uronic Acids

1969
Publisher Summary This chapter describes the function of aldonic and uronic acids. These are intermediates in carbohydrate oxidation and function in the biosynthesis of cellular constituents, and these play a vital role in mammals. According to a recent discovery, uronic acid was found to be an antecedent of L-ascorbic acid in those animals that are ...
