90(4):387–395 Recent attention to dietary fiber in wheat (Triticum aestivum L.) has invigorated research in the nonstarch carbohydrate arabinoxylan (AX). Arabinoxylan gels are commonly characterized to determine the feasibility of utilizing them in numerous applications such as drug delivery systems. The general characteristics of numerous types of arabinoxylan gels as well as their susceptibility to degradation are discussed in this manuscript. ChEBI Name arabinoxylan: ChEBI ID CHEBI:28427: Definition A member of the class of arabinoxylans that consists of a polymer chain of β-(1→4)-linked D-xylopyranose units, many of which are 2- or 3-substituted, or 2,3-disubstituted by α-L-arabinofuranosyl residues. ABSTRACT. Recent attention to dietary fiber in wheat ( Triticum aestivum L.) has invigorated research in the nonstarch carbohydrate arabinoxylan (AX). AX molecules are composed of a linear xylose backbone with arabinose substitutions along the backbone.

Arabinoxylan structure

The arabinoxylan ethers were characterized using mid-infrared FTIR spectroscopy and from principal components analysis, PCA, structural or physical variations between samples were visualized. To facilitate comparison of arabinoxylan structures, the 1 M KOH-soluble arabinoxylans from each of the grasses were treated with an endo-β-1,4-xylanase to generate xylo-oligosaccharides. These oligosaccharides were isolated by size-exclusion chromatography (SEC) and then structurally characterized using MALDI-TOF-MS and 1- and 2-dimensional 1 H-NMR spectroscopy.

AX typically has a large molecular weight and semi-flexible nature, which also impacts the three-dimensional structure ( Kiszonas, Fuerst, Luthria, & Morris, 2015 ). Arabinoxylans consist of a linear chain backbone of ß- d -xylopyranosyl (Xyl p) residues linked through (1 → 4) glycosidic linkages. α - l -Arabinofuranosyl (Ara f) residues are attached to some of the Xyl p residues at O-3, O-4, and/or at both O-2,3 positions, resulting in four structural elements in the molecular structure of arabinoxylans: monosubstituted Xyl p at O-2 or O-3, disubstituted Xyl p at O-2,3, and unsubstituted Xyl p (Fig.

AXs demonstrate many functional properties in food production and physiological processes during metabolism. The results have shown ispaghula husk and wheat bran to be very-highly-branched arabinoxylans consisting of linear Β-D-→l(4)-linked xylopyranose →Xylp) backbones to which a-L-arabinofuranose →Araf) units are attached as side residues via α-→1(3) and a-→l(2) linkages. The slowest fermenting wheat arabinoxylan additionally contained a complex trisaccharide side chain with two arabinoses linked at the O-2 and O-3 positions of an arabinose that is O-2 linked to the xylan backbone.

Depending on the source, arabinoxylans exhibit different molecular features, which are determinants Based on the structure and abundance of enzyme-resistant polymeric material and different oligosaccharides, the latter being identified with 'H-NMR analysis, present in the enzyme digests, a structural model is proposed for the arabinoxylans.
