The complexation of metal cations by d-galacturonic acid: a spectroscopic study
Carbohydrate Research, 2004Solid complexes of D-galacturonic acid (GalA) with cobalt(II), copper(II), nickel(II) and oxovanadium(IV) (1-4) were prepared and characterised. The metal-to-ligand molar ratio was 1:2 for complexes 1-3 and 1:1 for complex 4. The alpha- and beta-anomers of GalA were detected in all the complexes in solid state and in solutions.

New insights on the mechanism of oxidation of d-galacturonic acid by hypervalent chromium
Dalton Transactions, 2011The pollutant Cr(VI) is known to be very carcinogenic. In conditions of excess of Cr(VI), oxidation of D-galacturonic acid (Galur), the major metabolite of pectin, yields d-galactaric acid (Galar) and Cr(III). The redox reaction takes place through a multistep mechanism involving formation of intermediate Cr(II/IV) and Cr(V) species.

Effect of D-Galacturonic Acid on Hydration of Cementitious Materials
Journal of Materials in Civil Engineering, 2011The extent of modification of the hydration process in a cementitious material by external agents depends on its mix components. In this study, the effect of D-galacturonic acid on the hydration of fiber-reinforced engineered cementitious composites (ECC) and ordinary mortar was investigated. The final setting time was monitored as well as the flexural

There is only limited knowledge about the metabolic route for D-galacturonic acid catabolism in eukaryotic organisms; however such a metabolic route exists since many species of yeast and mould are able to utilise D-galacturonic acid. The metabolic route in bacteria is known since decades and the corresponding genes are identified.

Isomerization of d-galacturonic acid in neutral, aqueous solution
Carbohydrate Research, 1969Abstract : The isomerisation products from the treatment of D-glucuronic acid in an aqueous solution of pH 7 at 100 and 110C have been separated by anion exchange chromatography and identified. The predominant product was D-lyxo-5-hexulosonic acid and the others were L-ribo-5-hexulosonic, D-mannuronic, D-altruronic, and D-alluronic acid (the amounts of

Potentiometric titration of poly(α-D)galacturonic acid
1996Abstract A commercially available sample of poly(α-D)galacturonic acid, i.e. pectic acid, was characterized according to the size and shape of its molecule through the volumetric and transport properties of its aqueous solutions. Thus, the average molecular weight of polygalacturonic acid and its average degree of polymerization were estimated on the
