  2. 1. Quantum Chemical Studies of Radical Cation Rearrangement, Radical Carbonylation, and Homolytic Substitution Reactions

    Author : Daniel Norberg; Nessima Salhi-Benachenhou; Sten Lunell; Tim Clark; Uppsala universitet; []
    Keywords : Quantum chemistry; quantum chemistry; coupled-cluster; density functional theory; meta-GGA; reaction mechanism; potential energy surface; isomerization; fragmentation; dissociation; condensation; addition; SH2; hydrogen abstraction; iodine atom transfer; complex; weakly interacting system; hyperfine coupling constant; Kvantkemi;

    Abstract : Quantum chemical calculations have been performed to investigate radical cation rearrangement, radical carbonylation, and homolytic substitution reactions of organic molecules. The rearrangement of the bicyclopropylidiene radical cation to the tetramethyleneethane radical cation is predicted to proceed with stepwise disrotatory opening of the two rings. READ MORE

  4. 2. Biogenesis of the bc1 complex in mitochondria

    Author : Katharina Stephan; Martin Ott; Daniel Daley; Erika Fernandez-Vizarra; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Respiratory chain; bc1 complex assembly; mitochondrial protein biogenesis; molecular biology; yeast; Biochemistry; biokemi;

    Abstract : Mitochondria perform a variety of tasks, but the function they are most prominent for is the energy conversion to form ATP, the universal energy equivalent of the cell. The majority of this ATP is created by the oxidative phosphorylation system, consisting of the respiratory chain and the ATP synthase. READ MORE

  5. 3. Interaction of some molecules with complex surfaces

    Author : Andrea Resta; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Catalysis; Ethylene; CO.; Surface Science; Vicinal surface; Ethanol; Rh;

    Abstract : This thesis investigates the adsorption, decomposition and reactions of small molecules on flat, oxidised and vicinal surfaces of late transition metals. The main technique for these studies is high resolution core level spectroscopy (HRCLS). All the studies presented in the thesis are performed in Ultra High Vacuum (UHV). READ MORE

  6. 4. Analysis of Complex Biological Samples using Liquid Chromatography-Fourier Transform Ion Cyclotron Resonance Mass Spectrometry

    Author : Margareta Ramström; Jonas Bergquist; Per Håkansson; Karin Markides; Carol Robinson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; mass spectrometry; liquid chromatography; protein; proteomics; peptide; Fourier transform ion cyclotron resonance mass spectrometry; cerebrospinal fluid; amyotrophic lateral sclerosis; electrospray ionization; electron capture dissociation; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Abstract : Studies of protein and peptide expression are vital in order to understand complex biological systems. As demonstrated in this thesis, on-line packed capillary liquid chromatography-Fourier transform ion cyclotron resonance mass spectrometry (LC-FTICR MS) is a useful analytical tool for such studies.

  7. 5. MHC class I - Peptide binding and complex stability

    Author : Elna Follin; Antigen presentation; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The major histocompatibility class I (MHC-I) genes are highly polymorphic and the proteins that they encode play a crucial role in both the innate and the adaptive immune response. A MHC-I molecule consists of three parts, one polymorphic heavy chain, one invariant light chain, β2-microglobulin and a peptide of usually between 8-11 amino acids in length. READ MORE
