Visualizing Chiral Interactions in Carbohydrates Adsorbed on Au(111) by High-Resolution STM Imaging

Klaus Kern, Uta Schlickum, Stephan Rauschenbach

Carbohydrates are the most abundant organic material on Earth and the structural "material of choice" in many living systems. Nevertheless, design and engineering of synthetic carbohydrate materials presently lag behind that for protein and nucleic acids. ...

Identification of Mobility-Resolved N-Glycan Isomers

Thomas Rizzo, Robert Paul Pellegrinelli, Ahmed Ben Faleh, Stephan Warnke, Priyanka Bansal

ABSTRACT: Glycan analysis has evolved considerably during the last decade. The advent of high-resolution ion-mobility spectrometry has enabled the separation of isomers with only the slightest of structural differences. However, the ability to separate suc ...

Carbohydrate Self-Assembly at Surfaces: STM Imaging of Sucrose Conformation and Ordering on Cu(100)

Klaus Kern, Stephan Rauschenbach, Sabine Abb

Saccharides are ubiquitous biomolecules, but little is known about their interaction with, and assembly at, surfaces. By combining preparative mass spectrometry with scanning tunneling microscopy, we have been able to address the conformation and self-asse ...

Leather-Promoted Transformation of Glucose into 5-Hydroxymethylfurfural and Levoglucosenone

Paul Joseph Dyson, Felix Daniel Bobbink, Florent Menoud, Zhangjun Huang

The search for efficient catalysts frequently leads to new homogeneous and heterogeneous catalysts of increasing complexity, and sometimes common, natural, or hybrid natural/synthetic materials that could be used in catalysis are overlooked. For example, t ...

Carbohydrate stabilization extends the kinetic limits of chemical polysaccharide depolymerization

Jeremy Luterbacher, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Raquel Zambrano Varela

Polysaccharide depolymerization is an essential step for valorizing lignocellulosic biomass. In inexpensive systems such as pure water or dilute acid mixtures, carbohydrate monomer degradation rates exceed hemicellulose—and especially cellulose—depolymeriz ...

Cryogenic Vibrational Spectroscopy Provides Unique Fingerprints for Glycan Identification

Thomas Rizzo, Michael Zachary Kamrath, Chiara Masellis, Neelam Khanal

The structural characterization of glycans by mass spectrometry is particularly challenging. This is because of the high degree of isomerism in which glycans of the same mass can differ in their stereochemistry, attachment points, and degree of branching. ...
