  1. 1. Essentially Lipids : Analytical methods for the characterization of lipid materials

    Detta är en avhandling från Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm Univeristy

    Författare :Petter Olsson; Stockholms universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lipids; Chromatography; HPLC; Charged Aerosol Detection; Evaporative light scattering detection; mass spectrometry; Analytical Chemistry; analytisk kemi;

    Sammanfattning : This thesis describes analytical methods for chromatographic characterizations of lipids in biological and technical systems.Lipids are a group of compounds with a central role in all known forms of life. In addition to the biological roles, lipids are also components in many products of our daily usage. LÄS MER

  2. 2. Amylopectin - Interactions with Lipids and Proteins

    Detta är en avhandling från Food Technology, Lund University

    Författare :Henrik Lundqvist; Lunds universitet.; Lund University.; [2001]
    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.

  3. 3. Studies of bioactive lipids in cancer

    Detta är en avhandling från Stockholm : Department of Genetics, Microbiology and Toxicology, Stockholm University

    Författare :Vicky Chatzakos; Stockholms universitet.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lipids; Sphingolipids; N-acyl amino acids; cancer; molekylärgenetik; Molecular Genetics;

    Sammanfattning : Lipids are a broad class of molecules that, besides being a major form of energy storage and components of cell membranes, act as bioactive signalling molecules. N-acyl taurines are structurally related to endocannabinoids that are known to exert antiproliferative actions in a variety of cancer cells. LÄS MER

  4. 4. Exploring the Interplay of Lipids and Membrane Proteins

    Detta är en avhandling från Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Författare :Candan Ariöz; Stockholms universitet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry; Membrane lipids; membrane proteins; anionic lipids; membrane remodeling; intracellular vesicles; model membrane systems; glycosyltransferase; Escherichia coli; lipid composition; fatty acid modification; membrane curvature; bacterial homeoviscous adaptation;

    Sammanfattning : The interplay between lipids and membrane proteins is known to affect membrane protein topology and thus have significant effect (control) on their functions. In this PhD thesis, the influence of lipids on the membrane protein function was studied using three different membrane protein models. LÄS MER

  5. 5. Oxidation of fish lipids during gastrointestinal in vitro digestion

    Detta är en avhandling från Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Författare :Karin Larsson; [2016]

    Sammanfattning : Fish and many other marine organisms, contain long chain n-3 polyunsaturated fatty acids (LC n-3 PUFA), e.g. eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). EPA and DHA has shown beneficial effects in diseases related to inflammatory processes, such as cardiovascular diseases. LÄS MER
