An acidic arabinoxylan occurring in the hemicellulose I fraction (4% potassium hydroxide extract) of cell walls of immature barley plants was isolated and characterized by methylation and fragmentation analyses. The results indicated that the acidic arabinoxylan had a linear backbone chain of β-l, 4-D-xylose residues, about 50% of which were substituted at the 2 and/or 3 position, mainly with arabinofuranose and glucuronic acid residues.
