1. On the Formation of Supported Phospholipid Bilayers
Sammanfattning : Lipid bilayers are a central component of both the structure and function of biological membranes, like the one surrounding cells of living organisms. Since the lipid bilayer provides a host matrix for membrane proteins, which perform many of the specialized tasks in cells like energy, signal and material transduction, researchers have tried to develop artificial model membranes to study a variety of membrane protein functions.

2. Structure and Dynamics in Amphiphilic Bilayers: NMR and MD simulation Studies
Sammanfattning : Solid-state nuclear magnetic resonance (NMR) spectroscopy and molecular dynamics (MD) simulations were employed to study molecular structure and dynamics in amphiphilic bilayers. This thesis reports on method development and practical applications to two types of bilayer systems: simple cell membrane models composed of phosphatidylcholine lipids and cholesterol; and liquid crystals composed of ethyleneoxide-based surfactants often used in technological applications and in fundamental studies of amphiphile self-assembly.

3. Molecular Modeling of Cardiolipin
Sammanfattning : Biological membranes are assembled from many different lipids. Our understanding of membrane function and morphology is dependent on linking the properties of the lipids to the properties of the membranes. LÄS MER
4. Interfacial Properties of Lipid Liquid Crystalline Nanoparticles
Sammanfattning : Lipid liquid crystalline nanoparticles are studied for their potential as biocompatible carriers for pharmaceutical, food and cosmetic applications. Their potential as delivery vehicles is due to their nanometer size, their controllable structure and physical properties and their large carrying capacity of a wide range of molecules. LÄS MER
5. Studies on coactosin-like protein interaction with 5-lipoxygenase
Sammanfattning : Leukotrienes (LTs) are proinflammatory lipid mediators derived from polyunsaturated arachidonic acid, which is ester-bound at the sn-2 position of glycerol in cellular phospholipid bilayers. In LTs biosynthesis, 5-lipoxygenase (5-LO) represents the key enzyme, which catalyzes two initial steps. LÄS MER
