  1. 1. Greening peptide chemistry by using NBP as solvent for SPPS

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Andrea Ölander; [2022]
    Keywords : SPPS; Green chemistry; Peptide Synthesis; Organic chemistry; Organisk kemi; Chemistry;

    Abstract : The preferred method for synthesising therapeutic peptides today is by Solid-Phase Peptide Synthesis (SPPS). SPPS is a wasteful process, where the main component of the waste is hazardous solvents, i.e., N,N-dimethylformamide (DMF), N-methylpyrrolidone (NMP) or dichloromethane (DCM). READ MORE

  2. 2. Benchmarking a memetic algorithm for global all-atom protein-protein docking with backbone flexibility

    University essay from Lunds universitet/Kemiska institutionen

    Author : Vera Karlin; [2022]
    Keywords : biochemistry; EvoDOCK; algorithm; protein; iRMSD; DockQ; CAPRI; Chemistry;

    Abstract : Determining how proteins interact with each other to form complexes is very important for understanding both disease and cellular functions, but experimentally determining the structures of these complexes is both tedious and slow, which is why a great number of protein-protein docking algorithms have been developed to predict them. To this day, conformational changes in protein backbones have been one of the largest challenges when making docking predictions. READ MORE

  3. 3. Geological characterization of rock samples by LIBS and ME-XRT analytical techniques

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Nsioh Elvis Nkioh; [2022]
    Keywords : geological characterization; analytical techniques; LIBS; ME-XRT; SEM; element maps; SEM-EDS; secondary electrons; rock samples; automated ore microscopy; SEM-Zeiss Merlin; element weight percentages; element oxide percentages; scanning techniques; analytical methods; laser induced breakdown spectrometry; multi energy x-ray transmission; scanning electron microscope; carbon coating; mineralogical classification; element composition; rock chemistry; rock chemical composition;

    Abstract :      One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. READ MORE

  4. 4. Rare Earth Triflate/Alanine Catalysed Diels-Alder and Michael Reactions in Water and an Alternative Pyrrole Synthesis

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Albin Olsson; [2022]
    Keywords : Water; Green Chemistry; Synthesis; Organic Chemistry; Chemistry;

    Abstract : Large amounts of organic solvents are used within the field of chemistry and nearly everything is being discarded and is not reused. A way to reduce the environmental impact that this leads to is to use a safe and natural solvent that is easy to access, like water. READ MORE

  5. 5. Effects of plant polar lipids on postprandial glycemic regulation in healthy humans

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Yijia Yao; [2022]
    Keywords : plant polar lipid; meal study; clinical study; postprandial glycemic regulation; applied nutrition and food chemistry; Technology and Engineering;

    Abstract : In light of diabetes becoming a global discussion topic, some steps ought to be taken to help reduce the number of individuals suffering from the disease. Keeping good glycemic control through a healthy diet helps prevent diabetes and cardiovascular disease. Plant lipids are increasingly being studied for their postprandial effects on humans. READ MORE
