An improved HPAEC-PAD method for the determination of D-glucuronic acid and 4-O-methyl-D-glucuronic acid from polymeric and oligomeric xylan [PDF]
Glucuronic acid (GlcA) is an abundant substituent in hardwood xylan, and it is often found in its methylated form as methyl glucuronic acid (MeGlcA). GlcA and MeGlcA are sugar acids, bound to the xylose backbone at position O-2, and their presence can ...

Removal of glucuronic acid from xylan is a strategy to improve the conversion of plant biomass to sugars for bioenergy. [PDF]
BackgroundPlant lignocellulosic biomass can be a source of fermentable sugars for the production of second generation biofuels and biochemicals. The recalcitrance of this plant material is one of the major obstacles in its conversion into sugars. Biomass

Characterisation of three fungal glucuronoyl esterases on glucuronic acid ester model compounds. [PDF]
The glucuronoyl esterases (GEs) that have been identified so far belong to family 15 of the carbohydrate esterases in the CAZy classification system and are presumed to target ester bonds between lignin alcohols and (4-O-methyl-)d-glucuronic acid ...

A Hexasaccharide Containing Rare 2-O-Sulfate-Glucuronic Acid Residues Selectively Activates Heparin Cofactor II. [PDF]
Glycosaminoglycan (GAG) sequences that selectively target heparin cofactor II (HCII), a key serpin present in human plasma, remain unknown. Using a computational strategy on a library of 46 656 heparan sulfate hexasaccharides we identified a rare ...

MICROANALYSIS OF GLUCURONIC ACID AND GALACTURONIC ACID
Qualitative and quantitative determinations of uronic acids and uronides were carried out by conductometric and potentiometric titrations and paper chromatography.1. The dissociation of glucuronic acid lactone is very slow in neutral and acidic solutions.
