Synthesis of Glycosides of Glucuronic, Galacturonic and Mannuronic Acids: An Overview

Molecules, 2011
Uronic acids are carbohydrates present in relevant biologically active compounds. Most of the latter are glycosides or oligosaccharides linked by their anomeric carbon, so their synthesis requires glycoside-bond formation. The activation of this anomeric

Selective oxidation of uronic acids into aldaric acids over gold catalyst

, 2015
Herein, uronic acids available from hemicelluloses and pectin were used as raw material for the synthesis of aldaric acids. Au/Al2O3 catalyst oxidized glucuronic and galacturonic acids quantitatively to the corresponding glucaric and galactaric acids at ...

Carbon‐Negative Upcycling of Sewage Sludge into Superiorly Stable Gel Via Liquid‐Phase Utilization Strategy for Water‐Remediation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work developed a low‐temperature sludge hydrothermal coupled with gel crosslinking strategy which could upgrade the waste liquid generated from sewage sludge hydrothermal treatment into the hydrothermal‐liquid‐gel. The inventive hydrothermal‐liquid‐gel exhibited the enhanced pollutant removal capability, high synthetic stability, and superior ...

Quantifying Effects of OM–Cation Interactions on Mid‐Infrared FTIR Absorption Spectra of Polygalacturonic Acid

Journal of Plant Nutrition and Soil Science, EarlyView.
The composition of organic matter (OM) was explained by effects of OM–cation interactions using polygalacturonic acid (PGA) as model substance. These effects were analyzed by COO− absorption bands in mid‐FTIR spectra. The change in intensity and wavenumber ranges of COO− bands in FTIR was quantified.
