31. Analysis of lignin monomers and oligomers in technical lignins using chromatography and mass spectrometry
Sammanfattning : Lignin is the most abundant aromatic biopolymer on earth and has the potential to play an important role in the transition from an oil-based refinery to a biorefinery-based industry. The isolation of lignin from the biomass can be achieved by several different technical processes and isolated lignins are referred to as technical lignins in literature. LÄS MER
32. Photoinduced Electron and Energy Transfer in Π-Conjugated Systems
Sammanfattning : Photosynthesis is a fascinating process that provides food and oxygen. In this thesis, focus is on understanding and controlling the early processes of photosynthesis, namely photoinduced energy and electron transfer. LÄS MER
33. Oligomerization of human and bacterial frataxin : Structural and functional studies
Sammanfattning : Friedreich’s ataxia (FRDA) is an autosomal recessive neurodegenerative disease caused by defeciency in frataxin, a highly conserved protein central to iron homeostasis in mirochondria. The function of frataxin is related to its capability to bind, store and deliver iron to different biochemical process such as iron-sulfur cluster assembly and heme biosynthesis. LÄS MER
34. Domain swapping as a molecular mechanism in amyloidosis
Sammanfattning : Amyloidosis is a group of diseases characterized by a change in protein conformation resulting in aggregation and tissue deposition of amyloid fibrils. One variant of cystatin C, L68Q cystatin C, is highly amyloidogenic and persons carrying the corresponding gene suffer from massive cerebral amyloidosis leading to brain hemorrhage and death. LÄS MER
35. Capturing transient peptide assemblies associated with Alzheimer's disease : Native mass spectrometry studies of amyloid-β oligomerization
Sammanfattning : Correct folding of proteins is essential for maintaining a functional living cell. Misfolding and aggregation of proteins, where non-native intermolecular interactions form large and highly ordered amyloid aggregates with low free energy, is hence associated with multiple diseases.
