Tailored biocatalysis for dicarboxylic acid production: A versatile enzymatic approach to galactaric and glucaric acids

Bioresource Technology
The conversion of renewable biomass into value-added dicarboxylic acids, such as galactaric and glucaric acids, remains a significant challenge for the sustainable chemical industry, largely due to the lack of efficient and selective enzymatic processes.

Influence of the method of synthesis on the composition and structure of copper(II) complexes with galactaric acid

Russian Journal of Inorganic Chemistry, 2007
The influence of the conditions and the method of synthesis on the composition of copper(II) complexes with galactaric acid (H2Gala) has been studied. In aqueous and water-DMSO solutions, 1 : 1 complexes are formed. Depending on the procedure and conditions of the synthesis, CuGala · 4H2O, Cu(HGala)2 · 4H2O, and (CuOH)2Gala · 2H2O compounds have been ...

Simultaneous Production of Electricity and Galactaric Acid from Pectin with an Enzymatic Biofuel Cell

ECS Meeting Abstracts, 2016
Introduction Enzymes, which are reproducible catalysts, can catalyze selective and environmentally friendly production of platform chemicals from biomass, in simple systems. When the platform chemical-production is through one or more oxidation reactions, the electrons obtained from the substrate are ...

Multinuclear NMR study of the complexation of d-galactaric and d-mannaric acids with molybdenum(VI)

Polyhedron, 1994
The coordination compounds formed between MoVI and d-galactaric and d-mannaric acids, in aqueous solution, have been studied by 1H, 13C, 17O and 95Mo NMR spectroscopy, and compared taking into account the configuration of the ligands. In the pH range ca. 2–9, four major complexes are detected (in slow exchange at room temperature). The results point to

Structure–Property Relations in New Cyclic Galactaric Acid Derived Monomers and Polymers Therefrom: Possibilities and Challenges

Macromolecular Rapid Communications, 2018
AbstractIn order to fully exploit the potential of carbohydrate‐based monomers, different (and some new) functionalities are introduced on galactaric acid via acetalization, and subsequently, partially‐biobased polyamides are prepared therefrom via polycondensation in the melt.

Binding of calcium, lead, and copper(II) cations to galactaric and 2,5-furandicarboxylic acids and to D-galacturonic acid and its derivatives

Collection of Czechoslovak Chemical Communications, 1986
The binding of Ca2+, Pb2+, and Cu2+ ions to galactaric and 2,5-furandicarboxylic acids and of Pb2+ and Cu2+ ions to D-galacturonic acid, its α-methylglycoside, and (methyl-4-deoxy-α-D-galactopyranosid)uronic acid was evaluated in terms of the activity coefficients of the counter-ions and the degrees of their association with the carboxylate groups of ...
