Highly efficient and selective biocatalytic production of glucosamine from chitin

open access: yes, 2017
N-Acetyl glucosamine (GlcNAc) is one of the most abundant biomolecules on Earth and is cheaply available from chitin, a major component of crustaceans. The key step in the conversion of GlcNAc to high-value products is the de-N-acetylation to glucosamine,

Beyond FimH: Diversity and Relevance of Carbohydrate‐Binding Fimbrial Proteins in Escherichia coli

open access: yesChemBioChem, EarlyView.
This review discusses fimbrial lectins found in Escherichia coli (E. coli) other than FimH, which could be targeted to treat E. coli pathogenicity as an alternative to antibiotic treatment. Escherichia coli (E. coli) is responsible for multiple diseases in humans and animals.

Sustainable CO2 adsorbents prepared by coating chitosan onto mesoporous silicas for large-scale carbon capture technology [PDF]

open access: yes, 2015
In this article, we report a new sustainable synthesis procedure for manufacturing chitosan/silica CO2 adsorbents. Chitosan is a naturally abundant material and contains amine functionality, which is essential for selective CO2 adsorptions.

Gold‐Dithiocarbamato Glycoconjugates as Potential Anticancer Agents: Design, Physico‐Chemical Characterization and In Vitro Biological Activity

open access: yesChemBioChem, Accepted Article.
In order to develop new metal‐based glycoconjugates as potential anticancer agents, three gold(III)‐dithiocarbamato glycoconjugates of the type [AuIIIBr2(SSC‐Inp‐GlcN)] (Au3‐5), their gold(I)‐phosphine counterparts [AuI(SSC‐Inp‐GlcN)(PPh3)] (AuP3‐5) and gold(I)‐carbene analogues [AuI(SSC‐Inp‐GlcN)(Et2BzImy)] (AuC3‐5) (Inp: isonipecotic moiety; GlcN ...

A novel type of meso-diaminopimelic acid-based peptidoglycan and novel poly(erythritol phosphate) teichoic acids in cell walls of two coryneform isolates from the surface flora of French cooked cheeses [PDF]

open access: yes, 1993
The primary structure of the peptidoglycan and the teichoic acids of two coryneform isolates from the surface flora of French cooked cheeses, CNRZ 925 and CNRZ 926, have been determined.

Randomized Trial of Glucosamine and Chondroitin Supplementation on Inflammation and Oxidative Stress Biomarkers and Plasma Proteomics Profiles in Healthy Humans

open access: yesPLoS ONE, 2015
Background Glucosamine and chondroitin are popular non-vitamin dietary supplements used for osteoarthritis. Long-term use is associated with lower incidence of colorectal and lung cancers and with lower mortality; however, the mechanism underlying these ...

A Purification‐Free Strategy for the Electrochemical Oxidation of the Primary Hydroxy Group in Glycopyranosides

open access: yesChemElectroChem, EarlyView.
A straightforward protocol for the electrochemical oxidation of the primary hydroxy group in glycopyranosides is presented. It uses aqueous ammonia as a base and electrolyte, reticulated vitreous carbon (RVC) electrodes, and TEMPO as a mediator. The ammonium salts of the corresponding uronic acids are obtained in excellent yield upon evaporation of the

Fusion of secretory vesicles isolated from rat liver [PDF]

open access: yes, 1978
Secretory vesicles isolated from rat liver were found to fuse after exposure to Ca2+. Vescle fusion is characterized by the occurrence of twinned vesicles with a continuous cleavage plane between two vesicles in freeze-fracture electron microscopy.

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.
