  1. 21. Analytical approaches to the study of mucin glycosylation

    Författare :Kristina A Thomsson; Göteborgs universitet; []
    Nyckelord :mucins; O-linked glycosylation; mass spectrometry; cystic fibrosis; salivary mucins; sulfated oligosaccharides.;

    Sammanfattning : Mucins constitute the major protein component of the mucus layer, which covers the epithelial surfaces of the respiratory, the gastrointestinal and the genitourinary tracts. Mucins carry O-linked oligosaccharides which contribute to the molecule by 50-80 weight percent, and these can be highly diverse, with 50-150 different oligosaccharides found on a purified mucin population.

  3. 22. Synthesis of oligosaccharides for structural, conformational and molecular recognition investigations

    Författare :Peter Söderman; Inge Lundt; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; organisk kemi;

    Sammanfattning : Carbohydrates are involved cell-cell interaction. Synthesis of small and medium sized oligosaccharides is important to gain more understanding about the their physical properties that are crucial for their action in molecular recognition events. LÄS MER

  4. 23. Formation of carboxylic acids in rats and humans given indigestible carbohydrates Effects of monomeric composition, solubility, molecular weight and probiotics

    Författare :Ulf Nilsson; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carboxylic acids; Short-chain fatty acids; Fructo-oligosaccharides; Prebiotics; Probiotics; Näringslära; Nutrition;

    Sammanfattning : There is increasing evidence that fermentation in the large intestine is important for health, and that health-promoting effects are mediated by fermentation products such as butyric and propionic acid. As the formation of carboxylic acids (CAs) from various carbohydrates reaching the colon has been shown to vary, it is of great interest to identify food factors that could be of importance to this process.

  5. 24. Characterization and engineering of carbohydrate-active enzymes for biotechnological applications

    Författare :Noor Hassan; Christina Divne; Eva Nordberg Karlsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; se conversion; galacto-oligosaccharides; thermostability; propeptide; Bioteknologi; Biotechnology;

    Sammanfattning : Extremozymes are enzymes produced by microorganisms that live in extreme habitats. Due to their higher stability, extremozymes is attracting interest as biocatalysts in various industrial processes. In this context, carbohydrate-active extremozymes can be used in various processes relevant to the paper, food and feed industry. LÄS MER
