3. 2. Production and Characterisation of Aquaporins and Proton-Translocating Transhydrogenase

   Författare :Mikael Ekvall; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aquaporins; transhydrogenase; membrane proteins; x-ray chrystallography; structure; protein production; overproduction;

   Sammanfattning : Dissertation Abstract Water transport in eukaryotic cells is a highly regulated and fine-tuned process. Water channel protein known as aquaporins (AQPs), constitute the main cellular water transport system, preserving water homeostasis by maintaining specific selectivity-mechanisms. LÄS MER

   Författare :Lars Nilsson; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technological sciences; Egg yolk proteins; Competitiva adsorption; Field Flow Fractionation; Hydrophobically modified starch; Emulsions;

   Sammanfattning : The adsorption behavior of macromolecular emulsifiers is important in the understanding of their functionality. Understanding of the adsorption behavior can ultimately enable us to control emulsion properties. LÄS MER

5. 4. Structural studies of FocB and Transthyretin

   Författare :Ulrika Wikström Hultdin; Elisabeth Sauer-Eriksson; Inger Andersson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi;

   Sammanfattning : The molecular structure of a protein decides its function, its way to interact with other molecules. Using X-ray crystallography methods, a 3-dimensional, atomic model of a macromolecule can be determined. LÄS MER

7. 5. Microstructure of spray dried particles at different scales of drying

   Författare :Marine Nuzzo; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; morphology; confocal Raman microscopy; phase segregation; spray drying;

   Sammanfattning : Spray drying is a preferred method to produce dry powder of thermally sensitive materials such as food and pharmaceuticals. Drying conditions and formulation determine primary properties such as morphology and composition that finally provide functionality such as dissolution, encapsulation and flowability. LÄS MER
