  1. 21. Conversion of xylan into value-added products

    Författare :Reza Faryar; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; xylooligosaccharides; biosurfactant; prebiotic; xylan-based film; Lactobacillus brevis;

    Sammanfattning : Today’s high demand on finding sustainable energy sources, replacing petroleum-based products and the needfor healthier food alternatives have forced us to search for natural recoverable resources and explore their manyhidden applications. One such resource is xylan, which has gained much attention as possible raw material forvarious exploitations. LÄS MER

  3. 22. Fast Microwave-Enhanced Intra-, Pseudo-intra- and Intermolecular Heck Reactions

    Författare :Andreas Svennebring; Mats Larhed; Anja Sandström; Erik Van der Eycken; Uppsala universitet; []
    Nyckelord :Pharmaceutical chemistry; palladium; Heck reaction; chelation control; microwave; Farmaceutisk kemi;

    Sammanfattning : The Heck reaction is one of the most appreciated methods for carbon-carbon bond formation. Due to its mildness and ability to be tuned by additives, it often leaves few alternative competitive reactions. It has also proven easy to develop the reaction conditions in an environmentally benign direction. LÄS MER

  4. 23. Prebiotic Oligosaccharides from Xylan: Heat Pretreatment, Xylanase Hydrolysis, Utilization by Potential Probiotics and Evaluation in a Mouse Study

    Författare :Peter Falck; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; arabinoxylan; xylooligosaccharides; arabinoxylooligosaccharides; Bifidobacterium; Lactobacillus;

    Sammanfattning : Modulation of the gut microbiota with prebiotic oligosaccharides from partially hydrolyzed xylans can be part of the solution for reducing the occurrence of many health problems such as diabetes, cardiovascular disease and cancer. Prebiotics are carbohydrates that selectively stimulate health beneficial bacteria in the colon, restoring homeostasis to the gut environment. LÄS MER

  5. 24. Enzymatic hydrolysis coupled to hot water extraction for determination of flavonoids in plants

    Författare :Sofia Lindahl; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; extraction; flavonoids; quercetin; biocatalysis; beta-glucosidase; sustainable chemistry; hyphenation; molecularly imprinted polymers; onion;

    Sammanfattning : The word sustainability is more and more frequently used within the field of chemistry and in many other fields. Green or sustainable chemistry was introduced during the 90 ́s as a field of chemistry where the environmental and health impacts of processes and products are evaluated and improved. LÄS MER

  7. 25. Interactions Between Small Heat Shock Proteins and Substrate Proteins Mass Spectrometric Detection of Crosslinked Peptides to Map Protein-Protein Interactions

    Författare :Emma Åhrman; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein-protein interactions; Small heat shock proteins; Mass spectrometric peptide mapping; Proteins; enzymology; Proteiner; enzymologi;

    Sammanfattning : The small heat shock proteins (sHsps) are a widespread class of molecular chaperones existing in all organisms. During heat stress the sHsps protect other proteins from unfolding and aggregation. In plants the sHsps play an especially prominent part of the stress response. LÄS MER
