16. Prevention of hemolysis as a novel strategy to limit hemoglobin-mediated lipid oxidation in fish - towards a more sustainable use of fish raw materials
Sammanfattning : Hemoglobin (Hb) has been recognized as a main pro-oxidant in fish, causing fast and intense lipid oxidation. This thesis explores the hypothesis that maintaining red blood cells (RBCs) intact for an extended time during fish processing could delay Hb-mediated lipid oxidation. LÄS MER
17. Thiopurine S-methyltransferase - characterization of variants and ligand binding
Sammanfattning : Thiopurine S-methyltransferase (TPMT) belongs to the Class I S-adenosylmethionine-dependent methyltransferase (SAM-MT) super family of structurally related proteins. Common to the members of this large protein family is the catalysis of methylation reactions using S-adenosylmethionine (SAM) as a methyl group donor, although SAM-MTs act on a wide range of different substrates and carry out numerous biologically important functions.

18. Computational Modelling of Ligand Complexes with G-Protein Coupled Receptors, Ion Channels and Enzymes
Sammanfattning : Accurate predictions of binding free energies from computer simulations are an invaluable resource for understanding biochemical processes and drug action. The primary aim of the work described in the thesis was to predict and understand ligand binding to several proteins of major pharmaceutical importance using computational methods. LÄS MER
19. Lignin-carbohydrate complexes: Model compounds synthesis
Sammanfattning : In lignocellulose there is a recalcitrant interaction by covalent and non-covalent bonds called the lignin-carbohydrate complex. This interaction has been the subject of studies trying to unveil its chemical structure, to understand the mechanims involved in its formation and to determine its influence on practical applications such as the process of turning biomass into ethanol.

20. Toxicometabolomics and biotransformation product screening in single zebrafish embryos
Sammanfattning : Over the last decade environmental agencies worldwide have escalated their work to phase out animal testing for the purposes of chemical regulation. Meanwhile the number of commercially available chemicals and the requirements for hazard assessments have both increased, creating a large need for substitution of traditional in vivo assays with in vitro tests.
