Author information: (1)Beijing Advanced Innovation Center for Food Nutrition and Human Health, Beijing Technology and Business University (BTBU) , Beijing 100048, People's Republic of China. The chemical structure of rye arabinoxylan (rAX) was systematically modified, exploiting selective enzymes to mimic different naturally occurring xylans, i.e., its degree of substitution (DS) was decreased using α-l-arabinofuranosidase, and a controlled decrease in the degree of polymerization (DP) was performed using endo-1,4-β-d-xylanase. Fifty bread wheat (Triticum aestivum L.) cultivars were selected from the HEALTHGRAIN germplasm collection based on variation in their contents of total and water-extractable arabinoxylan. FT-IR spectroscopic mapping of thin transverse sections of grain showed variation in cell wall arabinoxylan composition between the cultivars, from consisting almost entirely of low-substituted arabinoxylan 2021-01-19 · The complex substrates were feruloylated arabinoxylan oligosaccharides (FAOX), de-starched wheat bran (DWB), and insoluble wheat arabinoxylan (InWAX).

It is made up of a backbone of β-1,4 linked xylose 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. Feruloylated arabinoxylans are the major non-starch polysaccharides from the cereal cell walls. 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.
