Structure determination of a novel uronic acid residue isolated from the exopolysaccharide produced by a bacterium originating from deep sea hydrothermal vents

Carbohydrate Research, 1996
The exopolysaccharide produced by the bacterium Alteromonas sp. strain 1644 originating from deep sea hydrothermal vents was shown to contain a novel glucuronic acid derivatives: 3-O-[(R)-1-carboxyethyl]-D-glucuronic acid. The structure of this compound was established on the basis of mass spectrometric data, methylation analysis, preparation of ...

Structural investigation of a uronic acid-containing polysaccharide from abalone by graded acid hydrolysis followed by PMP-HPLC–MSn and NMR analysis

Carbohydrate Research, 2015
A new strategy was applied to elucidate the structure of a polysaccharide from abalone gonad (AGSP). It was hydrolyzed by 0.05 M, 0.2 M, 0.5 M, and 2.0 M TFA at 100 °C for 1 h, sequentially. Every hydrolysate was ultrafiltrated (3000 Da) to collect oligo- and monosaccharides, and the final retentate was further hydrolyzed with 2.0 M TFA at 110 °C and ...

Studies on the Uronic Acid-Containing Glycoproteins of Fusarium sp. M7-1: II. The Primary Structures of the Low Molecular Weight Carbohydrate Chains of the Glycoproteins

The Journal of Biochemistry, 1992
The primary structures of the O-glycosidically linked oligosaccharides isolated from glycoproteins GP I and GP II of Fusarium sp. M7-1 were established. The oligosaccharides released by alkaline borohydride treatment from the glycoproteins were purified by Bio-Gel P-4 and HPLC.

Mass spectrometry of uronic acid derivatives. XI—Structure elucidation by mass spectrometry of aldobiouronic and pseudoaldobiouronic acids and their β-elimination products as per-O-methyl derivatives

Biological Mass Spectrometry, 1978
Electron impact mass spectra of a series of aldobiouronic and pseudoaldobiouronic acid per-O-methyl derivatives and of the corresponding 4,5-unsaturated analogues, found normally among the products of methylation of uronic acid containing disaccharides as a result of methylation accompanying beta-elimination, have been studied.

Synthesis of L-Iduronic Acid Derivatives: Crystal Structure of Methyl (Methyl 2,3,4-Tri-O-Acetyl-β-L-Idopyranosid)Uronate

Journal of Carbohydrate Chemistry, 1991
ABSTRACT Several L-iduronic acid derivatives were prepared by chemical synthesis including the reducing sugar, the α– and s-methyl glycosides and L-iduronolactone. The s-methyl glycoside, as well as two isomeric orthoesters, were the unexpected products of glycosylation of methyl (2,3,4-tri-O-acetyl-α-L-idopyranosyl bromide) uronate.

Koenigs–Knorr reaction of fusel alcohols with methyl (1-bromo-2,3,4-tri-O-acetyl-α-d-glucopyranosid)uronate leading to the protected alkyl glucuronides—crystal structures and high resolution 1H and 13C NMR data

Carbohydrate Research, 2012
Crystal structures and high resolution (1)H and (13)C NMR spectral data for methyl (alkyl 2,3,4-tri-O-acetyl-β-D-glucopyranosid)uronates (alkyl=methyl, ethyl, n-propyl, i-propyl, n-butyl, sec-butyl, i-butyl, n-pentyl, 2-methyl-1-butyl and 3-methyl-1-butyl) are presented.

Studies on the uronic acid-containing glycoproteins of Fusarium sp. M7-1: III. The primary structures of the acidic polysaccharides of the glycoproteins.

Journal of biochemistry, 1992
Two O-glycosidically linked acidic polysaccharides, AP I and AP II, were released, respectively, from glycoproteins GP I and GP II of Fusarium sp. M7-1 by alkaline borohydride treatment and purified by gel filtration chromatography. They were found to be apparently homogeneous on gel filtration chromatography and analytical ultracentrifugation.
