1. 1. α-synuclein interactions with lipid membranes

   Författare :Katarzyna Makasewicz; NanoLund: Centre for Nanoscience; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; alpha-Synuclein; lipid membranes; protein-lipid interactions; binding cooperativity; membrane remodeling; protei-lipid co-aggregation;

   Sammanfattning : α-synuclein is an intrinsically disordered protein implicated in synaptic vesicle trafficking at the synapse. Accumulation of α-synuclein in the form of amyloid deposits coincides with the loss of dopaminergic neurons in Parkinsons disease. LÄS MER

3. 2. Biomimetic Membranes: : Molecular Structure and Stability Studies by Vibrational Sum Frequency Spectroscopy

   Författare :Jonathan F.D. Liljeblad; Mark W. Rutland; Magnus C. Johnson; Tore Brinck; Lars Kloo; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Vibrational Sum Frequency Spectroscopy VSFS ; Langmuir monolayer; LB depositon; phospholipids; oxidation; biomimetic membranes; Surface and colloid chemistry; Yt- och kolloidkemi;

   Sammanfattning : In the research presented in this licentiate thesis the surface specific technique Vibrational Sum Frequency Spectroscopy, VSFS, combined with the Langmuir trough has been utilized to investigate Langmuir monolayers and Langmuir-Blodgett (LB) deposited mono- and bilayers of phospholipids. Their molecular structure, stability, and hydration were probed to gain additional understanding of important properties aiming at facilitating the use of such layers as model systems for biological membranes.

5. 4. Solid-State NMR Characterization of Lipid Membranes

   Författare :Vasco Castro; Arnold Maliniak; Göran Lindblom; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solid-State NMR; Membranes; Lipids; Glycolipids; Local Anesthetics; Hydration; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

   Sammanfattning : This thesis deals with the study of lipid bilayer systems by solid-state nuclear magnetic resonance. Two-dimensional 1H-13C separated local field experiments under magic-angle spinning were employed to investigate structural and dynamical modifications of cell membranes, resulting from the addition of compounds with some biological relevance.

7. 5. Amylopectin - Interactions with Lipids and Proteins

   Författare :Henrik Lundqvist; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; binding isotherm; isothermal titration calorimetry; differential scanning calorimetry; retrogradation; alpha-lactalbumin; beta-lactoglobulin; whey protein; surfactant; lipid; exterior chain length; barley; potato; starch; amylopectin; amylose; Food and drink technology; Livsmedelsteknik; Proteins; enzymology; Proteiner; enzymologi; Lipids; steroids; membranes; Lipider; steroider; mebran;

   Sammanfattning : Starch is a common ingredient in many products, influencing properties such as viscosity, stability, sensory properties and appearance. These properties and how they change with time in the process called retrogradation are dependent on the structure of starch and its interaction with other components such as lipids and proteins.
