  1. 1. Lipid Self-Assembly and Lipase Action

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; specific activity.; Physical chemistry; Fysikalisk kemi; vesicles; cubosomes; liquid crystalline phases; sodium oleate; oleic acid; diolein; monoolein; Oleic acid based acyl glycerols; Thermomyces lanuginosa lipase;

    Sammanfattning : In this thesis the action of the Thermomyces lanuginosa lipase (TLL) on "real" substrates, that is, lipid aggregates - vesicles, micelles, emulsions, gels and liquid crystals is discussed. Even for a pure triolein, the system becomes quite complex as the lipolytic process starts, both in terms of structure and composition, involving 5 additional components - diolein (DO), monoolein (MO), oleic acid (OA), sodium oleate (NaO) and glycerol .

  3. 2. Protein complexes : assembly, structure and function

    Författare :Kristina Wilhelm; Ludmilla Ludmilla Morozova-Roche; Catharina Svanborg; Umeå universitet; []
    Nyckelord :HAMLET; ELOA; lysozyme; amyloid; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning :  Most proteins must fold into their native conformations to fulfil their biological functions. Failure of proteins to fold leads to cell pathology and a broad range of human diseases referred to as protein misfolding disease, e.g., Alzheimer’s disease, Parkinson’s disease, and type II diabetes.

  4. 3. Protein Complexity via Non-Native States: Binding, Stability, and Structural Studies of Calbindin D9k and HAMLET (Human alpha-lactalbumin Made LEthal to Tumor cells)

    Författare :Jonas Fast; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; apoptosis; oleic acid; HAMLET; kinetic trap alpha-lactalbumin; calbindin; calcium; Metabolism; Biokemi; metabolism;

    Sammanfattning : Using optical spectroscopy, nuclear magnetic resonance (NMR), and differential scanning Calorimetry (DSC), I have studied two different calcium binding proteins that can form kinetically trapped altered states. Calcium is very important in numerous biological processes such as blood coagulation, signal transduction, muscle contraction and bone formation. LÄS MER

  5. 4. Structure and stability of liposomes : Interactions with micelle- forming surfactants

    Författare :Mats Silvander; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : The stability of phospholipid lipomes interacting with micelle-forming surfactants was studied under physiological conditions (150 mM NaCl and pH=7.4 unless otherwise stated) mainly by use of cryo-TEM and fluorescence. LÄS MER

  7. 5. Structure-function analysis of HAMLET (human alpha-lactalbumin made lethal to tumor cells)

    Författare :Jenny Pettersson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alpha-lactalbumin HAMLET oleic acid protein folding tumor cell death;

    Sammanfattning : The human genome sequence encodes fewer proteins than expected, suggesting that one protein can have several functions and adjust their structure to meet different structural demands. Changes in tertiary structure have mostly been associated with disease and the most striking example is the prion protein, which changes from a mixed alpha-helical and beta-sheet conformation to the beta-sheet rich, disease causing iso-form.
