  • Title: Isolation of diferulic bridges ester-linked to arabinan in sugar beet cell walls.
    Author: Levigne S, Ralet MC, Quéméner B, Thibault JF.
    Journal: Carbohydr Res; 2004 Sep 13; 339(13):2315-9. PubMed ID: 15337461.
    Abstract:
    After degradation of sugar beet cell walls with Driselase and fractionation of the solubilised products by hydrophobic interaction chromatography, a dehydrodiferuloylated oligoarabinan was isolated. Its structure was assigned to two dimers of (1-->5)-linked arabinose units esterified by a central 8-O-4' ferulic dimer. These results provide the first direct evidence that pectic arabinans in sugar beet cell walls may be covalently cross-linked through dehydrodiferulates.
