Abstract Five naturally occurring hexuronic acids and several hexuronic acid-containing oligosaccharides were separated and identified by high voltage paper electrophoresis, using one of the following buffers. (i) Pyridine-acetic acid-water (1:10:89, by volume), the pH of which was adjusted to 2.3–3.5 with 98% formic acid.

Improved analytical method for the hexuronic acids at the reducing terminals of glycosaminoglycans
Journal of Proteomics, 1984When endo-uronidases act on glycosaminoglycans, the reaction products have hexuronic acid residues at the reducing terminals. An analytical method for hexuronic acids at the reducing terminals was devised for hyaluronate oligosaccharides having hexuronic acid residues at the reducing terminals.

IN connexion with experiments under the direction of Dr. L. J. Harris1 on the ro1e of the suprarenal gland in vitamin C metabolism, we have investigated the silver nitrate staining capacity of glands taken from normal and scorbutic animals. It will be recalled that long before the identity of vitamin C with hexuronic acid was postulated2,3, Szent ...

Hexuronic Acid Dehydrogenase of Agrobacterium tumefaciens
Journal of Bacteriology, 1969Growth of Agrobacterium tumefaciens on d -glucuronic acid (GlcUA) or d -galacturonic acid (GalUA) induces formation of hexuronic acid dehydrogenase [ d -aldohexuronic acid: nicotinamide adenine dinucleotide (NAD) oxidoreductase].

A simple method for the detection and quantitative determination of hexuronic acids and pentoses
Analytical Biochemistry, 1974Abstract The present report describes a new and simple method for the detection and quantitative determination of pentoses and hexuronic acids either separately or in a mixture. The method involves treatment of the sample with sulfuric acid followed by the addition of harmine and then cysteine. Hexuronic acids produce a pink color with harmine, while

Abstract Two modifications of the carbazole reaction of hexuronic acids are described which differ from the original reaction by the concentration of acid, the temperature, and the duration of heating. The different hexosaminohexuronides show very different extinction coefficients in these two reactions which can be used for the differentiation of ...
