    Sammanfattning : A new kind of lipid/polymer composite particle, consisting of a biodegradable polymer matrix with well-defined lipid domains, has been created. The lipid used is the water-swelling lipid monoolein (MO), which forms a reversed bicontinuous cubic diamond structure in aqueous solutions. LÄS MER

  3. 3. On the crystallization of membrane proteins in lipidic sponge and cubic phases

    Författare :Pia Jeanette Hindrichsen; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; monoolein MO ; selachyl alcohol; cubic phase; sponge phase; small angle X-ray scattering; protein crystallization; phytantriol PT ;

    Sammanfattning : Membrane proteins are involved in many important biological processes and in order to understand their mechanism, their three-dimensional structures need to be elucidated to high resolution by for example X-ray crystallography. However, there is only limited structural knowledge for membrane proteins which is partly explained by the difficulties in obtaining well-diffracting crystals. LÄS MER

  4. 4. Lipidic Cubic Phase Microcrystallization and its Application in Serial Crystallography

    Författare :Rebecka Andersson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Structural biology; Lipidic Cubic Phase; Cytochrome c oxidase; Serial Crystallography;

    Sammanfattning : Every living organism contain a cell membrane which is an important cell structure with a vast variety of different functions such as cell signaling, transportation and energy production. One of the most important functions is to produce energy for the cell to thrive. LÄS MER

  5. 5. Lipid bilayers versus monolayers- Sponge phases and skin lipid domains

    Författare :Katarina Ekelund; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fatty acids; Langmuir-Blodgett films; AFM; domains; stratum corneum; bilayer curvature; lipids; glycerol monooleate; phase behaviour; sponge phase; L3 phase; Livsmedelsteknik; cholesterol; Food and drink technology;

    Sammanfattning : The L3, or sponge, phase is a thermodynamically stable isotropic liquid consisting of a surfactant membrane in aqueous solution. A solvent induced L3 phase is shown in systems of solvent, monoolein and water. LÄS MER
