Arabinoxylan is the main group of hemicellulosic polysaccharides that are present in the cell walls of monocot grass crops and hence in cereal grains. The arabinoxylan polysaccharides consist of a backbone of β-(1→4)-linked xylopyranosyl residues, which carry arabinofuranosyl moieties, hence the term arabinoxylan.

Recent works provide evidence of the prebiotic potential of arabinoxylan-derived oligosaccharides (A)XOS. In this study, we developed a structural analysis for Visar resultat 1 - 5 av 28 avhandlingar innehållade ordet arabinoxylan. of prebiotic oligosaccharides : Applied bioinformatics of glycoside hydrolases. Application of nano-probe NMR for structure determination of low nanomole amounts of arabinoxylan oligosaccharides fractionated by analytical HPAEC-PAD.
However, the mechanisms by which bifidobacterial strains break down these compounds in the colon is still unknown. Due to their potential prebiotic properties, arabinoxylan-derived oligosaccharides [(A)XOS] are of great interest as functional food and feed ingredients. While the (A)XOS metabolism of Bifidobacteriaceaehas been extensively studied, information regarding lactic acid bacteria (LAB) is still limited in this context. Upon hydrolysis of arabinoxylans by enzymes, arabinoxylan oligosaccharides are produced. Many gut microbes are capable of degrading arabinoxylans, such as lactobacilli, Bacteroides, Roseburia eubacterium, Faecalibacterium prausnitzii, Bi. animalis, and nonpathogenic clostridia (Grootaert et al., 2009). 2015-04-07 · To characterize the binding epitopes of these powerful molecular probes a library of eleven plant arabinoxylan oligosaccharides was produced by automated solid-phase synthesis. Modular assembly of oligoarabinoxylans from few building blocks was enabled by adding (2-naphthyl)methyl (Nap) to the toolbox of orthogonal protecting groups for solid-phase synthesis.
Ball milling was used for producing complex arabinoxylan oligosaccharides (AXOS) and low molecular mass arabinoxylans (AX) from wheat bran, pericarp-enriched wheat bran, and psyllium seed husk. The arabinose to xylose ratio of the samples produced varied between 0.14 and 0.92, and their average degree of polymerization (avDP) ranged between 42 and 300.

For example, glycolipids have an important role in the immune response. They are normally present as glycans : oligosaccharide chains linked to lipids or to compatible amino acid side chains in proteins , by N - or O - glycosidic bonds . Arabinoxylan oligosaccharides (AXOS) are considered as DF with prebiotic potential, but so far no studies have investigated their metabolic effects in humans. Arabinoxylan Oligosaccharides With Different DP Trigger Calcium Influxes in Arabidopsis In order to investigate whether pentose-based structures could be sensed by Arabidopsis, we decided to analyze in a first instance the capacity to trigger Ca 2+ influxes of different commercial polymeric structures ( Figure 2A ). A new class of candidate prebiotics is that of the arabinoxylan oligosaccharides (AXOS). AXOS are derived from arabinoxylans, complex carbohydrates found in the cell walls of the starch endosperm and the aleurone layer (Fincher & Stone, 1986) and in pericarp tissues (Maes & Delcour, 2002) of cereals. Arabinoxylan is the main group of hemicellulosic polysaccharides that are present in the cell walls of monocot grass crops and hence in cereal grains.

Tolerance of arabinoxylan-oligosaccharides and their prebiotic activity in healthy subjects: a randomised, placebo-controlled cross-over study. Cloetens L(1), Broekaert WF, Delaedt Y, Ollevier F, Courtin CM, Delcour JA, Rutgeerts P, Verbeke K. arabinoxylan oligosaccharides (A)XOS were studied as model systems by hydrophilic interaction UPLC-MS2 in negative ion resolution mode to identify potential oxidation products. An in-depth identifi-cation of acidic (A)XOS oxidation products derived from TEMPO-mediated oxidation provided novel Inulin-type fructans (ITF) and arabinoxylan oligosaccharides (AXOS) are broken down to different extents by various bifidobacterial strains present in the human colon. To date, phenotypic heterogeneity in the consumption of these complex oligosaccharides at the strain level remains poorly studied. To examine mechanistic variations in ITF and AXOS Objectives: We assessed whether wheat bran extract (WBE) containing arabinoxylan-oligosaccharides (AXOS) elicited a prebiotic effect and modulated gastrointestinal (GI) parameters in healthy preadolescent children upon consumption in a beverage.
