Definition of oligosaccharide in English:



  • A carbohydrate whose molecules are composed of a relatively small number of monosaccharide units.

    ‘All carbohydrates can be classified as either monosaccharides, oligosaccharides or polysaccharides.’
    • ‘Prebiotics are complex carbohydrates - oligosaccharides, such as inulin and short-chain sugars.’
    • ‘Enzymes that act on substrates such as polypeptides, nucleic acids, oligosaccharides, or lipid membranes often interact with more than one substrate molecule.’
    • ‘In addition to sucrose, the oligosaccharides raffinose and stachyose were also detected, but only from 55 DAA.’
    • ‘Fetuin contains six oligosaccharides chains, namely three carbohydrate units O-linked to Thr or Ser residues and three complex glycans, N-linked to Asn residues.’
    • ‘The non-structural carbohydrates in shallots and onions include glucose, fructose and sucrose together with oligosaccharides, the fructans.’
    • ‘Di- and oligosaccharides are replaced by monosaccharides, while dehydrins and other desiccation-related proteins disappear.’
    • ‘Because each monosaccharide can link to more than one other monosaccharide, oligosaccharides can be branched.’
    • ‘Moreover, the formation of lipid rafts is thought to be favored by hydrogen bonding among the oligosaccharides in sphingolipids.’
    • ‘These calculations indicate that the strength of key mannose-protein interactions at the monosaccharide site is preserved in both the oligosaccharides.’
    • ‘There was no measurable incorporation of C into sucrose, hexoses or the raffinose family of oligosaccharides at any stage of the incubations.’
    • ‘Pathway by which the synthesis and transfer of the lipid-linked oligosaccharide unit takes place at the membrane of the ER.’
    • ‘Raffinose, as well as other members of the raffinose family of oligosaccharides, are important phloem transport and storage carbohydrates for many plants.’
    • ‘A major proportion of the soluble carbohydrates was made up of the raffinose series oligosaccharides, raffinose and stachyose.’
    • ‘Glucose accumulation rate during storage increased significantly with seed water content, which suggested the occurrence of greater sugar hydrolysis from sucrose and oligosaccharides.’
    • ‘Unspecific porins have repeatedly been described as passive, water-filled channels facilitating the diffusion of ions and polar molecules up to the size of trimeric oligosaccharides.’
    • ‘Moreover, some authors have suggested that seed sugar content, particularly the ratio of oligosaccharides to sucrose, might be used as an indicator of seed vigour and storability.’
    • ‘Complex N-linked oligosaccharides are negatively charged if they contain sialic acid.’
    • ‘As well as the binding functionality provided by the biochemically-specific moieties they contain, the oligosaccharide might impart a steric stiffness to the polypeptide core.’
    • ‘This may be explained by the difference in interaction of the tip with the polar zwitterionic PC headgroups and the anionic oligosaccharide headgroups of the ganglioside.’
