    Sammanfattning : Ubiquinones are a group of fat-soluble molecules present in many biological membranes. The most abundant version in humans, ubiquinone-10 (Q10), plays an important role in the mitochondrial respiration chain and also functions as a powerful antioxidant. Accumulating evidence suggests that Q10 also could have other functions in the membrane. LÄS MER

  3. 2. Responding Model Membranes. Lipid Phase Behaviour, Domain Formation and Permeability

    Författare :Emma Sparr; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Water and solute flux; Gradients; Monolayer; Two-dimensional crystals; Line activiy; Osmotic stress; Interlamellar forces; Phospholipid-cholesterol interactions; Phase transitions; Bilayer stack; Stratum corneum; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : This thesis concerns the interplay between the lipid phase behaviour, domain formation and the permeability of bilayer membranes. An essential part of this work has been the understanding of the phase transitions and equilibrium properties of lipid bilayers. LÄS MER
