1. 6. Block syntheses of complex oligosaccharides

   Författare :Hans Lönn; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The block synthesis concept has been applied for the preparation of complex glycoprotein oligosaccharides. A new glycosylation method designed for block syntheses of complex oligosaccharides is described. The synthesis of a highly functionalized disaccharide component of the capsular antigen from Streptococcus pneumoniae type 1 is also discussed.. LÄS MER

3. 7. Conformational Dynamics of Carbohydrates Studied by NMR Spectroscopy and Molecular Simulations

   Författare :Jennie Östervall; Göran Widmalm; C. Allen Bush; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; NMR; Molecular Dynamics; Conformation; Dynamics; Residual Dipolar Couplings; Cyclodextrins; Oligosaccharides; Organic chemistry; Organisk kemi;

   Sammanfattning : Carbohydrates play important roles in biological processes. Their function is closely related to their conformation. In this thesis, conformational studies of carbohydrates by NMR spectroscopy and molecular dynamics computer simulations are described. LÄS MER

4. 8. Pea-Protein Products for Food Applications Methods for Improving Iron and Zinc Availability

   Författare :Mattias Fredrikson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pea-protein; phytate; phytase-enzyme; oligosaccharides; phytate-degradation; ion chromatography; inositol-phosphate; iron and zinc availability; pea-protein purification;

   Sammanfattning : The thesis deals with some aspects of and possibilities for the production of pea protein with improved nutritional and physiological qualities. The improved pea protein can be used as a beneficial alternative to soya protein in food applications, such as infant formula. LÄS MER

5. 9. Content and Distribution of Short-Chain Fatty Acids in the Hindgut of Rats Fed Various Sources of Indigestible Carbohydrates

   Författare :Åsa Henningsson; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rats; red kidney beans; Nutrition; Näringslära; oligosaccharides; non-starch polysaccharides; resistant starch; dietary fibres; indigestible carbohydrates; short-chain fatty acids; fermentation;

   Sammanfattning : There is increasing evidence that short-chain fatty acids (SCFA) formed by colonic fermentation of indigestible carbohydrates have beneficial physiological effects. Butyric acid is the main energy substrate for the colonic mucosa and has been implicated as important in the prevention and treatment of diseases of the colonic mucosa, such as distal ulcerative colitis and cancer.

7. 10. Thermostable glycosidases and glycosynthases as biocatalysts in green chemistry applications

   Författare :Tania Pozzo; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Green chemistry; 3D sturcture; Glycosyl hydrolases; Glycosynthases; Alkyl glucosides; Oligosaccharides; Flavonoids;

   Sammanfattning : The constant need to develop environmental friendly processes using renewable raw materials and to reduce harmful waste production motivates the present investigation focusing on biocatalyst development for enzymatic synthesis, a biotechnological approach in the field of green chemistry. At first, structural functional experiments were made for a β-glucosidase from T. LÄS MER
