  1. 1. Enzymes for selective decoupling of woody biomass: From fundamentals to industrial potential

    Författare :Jenny Arnling Bååth; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignocellulose; glucuronoyl esterase; polysaccharide acetylation; carbohydrate esterase family 15; woody biomass; materials biorefinery; enzyme accessibility; lignin-carbohydrate bonds; mannanase; galactoglucomannan;

    Sammanfattning : The need for an economy based on renewable materials has resulted in growing interest in the use of woody biomass in a wider field of application. However, the chemical complexity of lignocellulose and the dense structure of wood pose challenges in its processing. LÄS MER

  3. 2. Multifunctional carbohydrate-based soft materials from cereal by-products

    Författare :Secil Yilmaz Turan; Francisco Vilaplana; Rosana Moriana; Amparo Jiménez Quero; Anna Ström; KTH; []
    Nyckelord :wheat bran; corn bran; hemicellulose; arabinoxylan; ferulic acid; subcritical water extraction; acetylation; films; hydrogels; crosslinking; regeneration; antioxidant activity; vetekli; majskli; hemicellulosa; arabinoxylan; ferulsyra; subkritisk vattenextraktion; acetylering; filmer; hydrogeler; tvärbindning; regeneration; antioxidant aktivitet; Bioteknologi; Biotechnology;

    Sammanfattning : Cereal production generates large quantities of by-products every year, which still remain underutilized. The hemicellulose fractions from cereal by-products are anticipated to play an important role in tomorrow's sustainable and bio-based circular economy. LÄS MER

  4. 3. Synthesis of oligosaccharides related to the capsular polysaccharide of Neisseria meningitidis serotype A

    Författare :Peter Teodorovic; Stefan Oscarson; Mikael Elofsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Sammanfattning : In order to find suitable stable vaccine candidates against Neisseria meningitidis group A, several structures related to the capsular polysaccharide have been synthesised. The first part of the thesis describes the synthesis of C-phosphonate analogues starting from glucose. LÄS MER

  5. 4. Tumor Selective Antiproliferative Naphthoxylosides

    Författare :Ulrika Aili; Glykobiologigruppen; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glycosaminoglycan; proteoglycan; heparan sulfate; xyloside; naphthoxyloside; histone H3 acetylation;

    Sammanfattning : Proteoglycans (PG) are highly anionic macromolecules consisting of a core protein covalently substituted with long unbranched polysaccharide chains called glycosaminoglycans (GAGs). PGs are central components in multicellular organisms, and they may occur in the extracellular matrix (ECM), at the cell surface, or in the secretory pathway. LÄS MER

  7. 5. NMR spectroscopy in structural and conformational analysis of bacterial polysaccharides

    Författare :Carolina Fontana; Göran Widmalm; Sven Müller-Loennies; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear Magnetic Resonance; carbohydrates; O-antigen polysaccharide; organisk kemi; Organic Chemistry;

    Sammanfattning : Carbohydrates constitute one of the three major classes of biomolecules found in all living cells and, unlike nucleic acids and proteins, their polymeric structures are not based on a template. The structural diversity of these molecules confers them an enormous capacity to encode information in biological systems, acting as efficient mediators in the interaction of the cell with the environment.
