Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

Genetic Locus and Structural Characterization of the Biochemical Defect in the O-Antigenic Polysaccharide of the Symbiotically Deficient \u3cem\u3eRhizobium etli\u3c/em\u3e Mutant, CE166 [PDF]

open access: yes, 2003
The O-antigen polysaccharide (OPS) of Rhizobium etli CE3 lipopolysaccharide (LPS) is linked to the core oligosaccharide via an N-acetylquinovosaminosyl (QuiNAc) residue.

Unveiling the Potential of a New β‐Cyclodextrin‐Suxibuzone Conjugate in Proteasome Regulation

open access: yesChemMedChem, EarlyView.
A novel β‐cyclodextrin‐suxibuzone conjugate enhances chymotryptic‐like activity of the 20S proteasome in a dose‐dependent manner. It remains stable and is internalized in SH‐SY5Y cells for 24 h. These findings suggest therapeutic potential for proteasome‐related disorders through targeted proteasome activation.

Can Conformers Be Identified via Cyclic Ion Mobility Mass Spectrometry? Hexosamine Epimers Reveal Ultrastable Ring Structures

open access: yesChemistry–Methods, EarlyView.
It was demonstrated how carbohydrate ring structures can be separated and identified using cyclic ion mobility mass spectrometry, making solid‐, solution‐, and gas‐phase structures comparable. In addition, it was determined which collisional cross‐section prediction or calculation method is the best suited for carbohydrates.

Rapid and Reliable Conformational Analysis of Glycans by Small Angle X‐Ray Scattering Guided Molecular Dynamics Simulations

open access: yesChemPhysChem, EarlyView.
By explicitly accounting for the conformational dynamics and hydration effects, the molecular dynamics simulations accurately predicted the small‐angle X‐ray scattering intensities of two glycan hairpins with similar primary sequences. This approach enables the resolving their intricate conformational properties, including distinct secondary structures,

Lipopolysaccharide (LPS, endotoxin) of Proteus bacteria-chemical structure, serological specificity and the role in pathogenicity [PDF]

open access: yes, 2008
Lipopolysaccharides (LPS) of Gram-negative bacteria are composed of three regions: О-specific chain (OPS), the core oligosaccharide and lipid A. All three regions of Proteus LPS were studied. The differences in the structure of OPS serve as the basis

A pH‐Responsive Synthetic Receptor for Switchable Binding of Carbohydrates

open access: yesChemPlusChem, EarlyView.
A diaminocarbazole macrocyclic receptor, designed for disaccharide recognition in water, exhibits distinct binding properties under alkaline versus neutral pH conditions. Carbohydrates are selectively recognized under alkaline conditions, whereas release of the bound guest occurs at physiological pH, effectively behaving as a pH‐switchable carbohydrate
