    Sammanfattning : Consumption of berries and pulses can protect against atherosclerosis and other metabolic diseases, by modulating plasma lipid profile, gut microbiota, and microbiota-dependent metabolites. These nutritional benefits are often attributed to high content of polyphenols (flavonoids and phenolic acids) and dietary fiber. LÄS MER

  3. 2. Modelling of molybdopterin-dependent enzymes

    Författare :Anders Thapper; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; enzymes; transition state; intermediate; mechanism; molybdopterin; density functional theory; model systems; oxygen atom transfer; molybdenum; tungsten; Oorganisk kemi; Chemistry; Kemi;

    Sammanfattning : The thesis deals with models for molybdopterin-dependent enzymes. Several model systems containing molybdenum or tungsten have been prepared and characterised, and their reactivity with oxygen atom acceptors and donors have been investigated. LÄS MER

  4. 3. Investigation of Coordination Modes of Organosulfur Ligands to osmium and Rhodium Carbonyl Clusters- Possible Relevance to Hydrodesulfurization Reactions

    Författare :Nitsa Kiriakidou-Kazemifar; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thioethers; thiols; HDS processes; organosulfur compounds; polynuclear metal complexes; Metallorganisk kemi; Organometallic chemistry; thiophenes;

    Sammanfattning : The coordination and fundamental transformations of organosulfur compounds to polynuclear metal complexes has been studied as models for possible surface species in industrial HDS processes. Reactions between [Os3(CO)11(NCMe)] and various thiols have been studied by UV-Vis, IR and NMR spectroscopy and all experimental findings indicate that the reactions proceed via a two-step consecutive process involving the intermediate [Os3(CO)11(RSH)], which contains an agostic Os-H-S interaction, and which leads to the formation of the final product [Os3(CO)10(m-H)(m-SR)].
