1. Multivariate Analysis of 2D-NMR Spectroscopy : Applications in wood science and metabolomics
Sammanfattning : Wood is our most important renewable resource. We need better quality and quantity both according to the wood itself and the processes that are using wood as a raw material. Hence, the understanding of the chemical composition of the wood is of high importance. LÄS MER
2. Fundamental Aspects of Lignin Carbohydrate Complexes (LCC) : Mechanisms, Recalcitrance and Material concepts
Sammanfattning : Covalent bonds between lignin and carbohydrates, forming a matrix referred to as lignin carbohydrate complexes (LCC), remain one of the most controversial topics in wood chemistry. A key issue is whether they are formed during chemical and mechanical pretreatments of the compact wood structure or actually present in wood prior to isolation. LÄS MER
3. Glutaredoxin 3 from Escherichia coli : NMR structure analysis and structural aspects of the enzymatic mechanism
Sammanfattning : The structure of Escherichia coli glutaredoxin 3 (Grx3) was investigated using NMR spectroscopy in combination with isotope labeling. Nearly complete sequence specific assignment were obtained for the reduced Grx3 using a 15N enriched protein sample. LÄS MER
4. Protected Lignin Biorefining: Fundamental Insights on Lignin Reactivity
Sammanfattning : The potential to utilize lignin, which constitutes as much as 15-30% of the biomass, needs further evaluation. In the transition towards a bioeconomy, lignin has the potential to replace fossil-based phenols. Attempts to valorize the available technical lignins are ongoing; however, that lignin suffers from molecular heterogeneity. LÄS MER
5. Conformations of Flexible Oligosaccharides : Molecular Simulations and NMR spectroscopy
Sammanfattning : The conformational preferences of several oligosaccharides are investigated herein using a combination of NMR spectroscopy and molecular dynamics (MD) simulations, focusing on the torsion angles associated with the glycosidic linkages.Strategies for obtaining usable J-HMBC spectra for carbons with an adjacent 13C label are described.
