Variations of glucuronoxylo-oligosaccharides found in F0s, all containing a xylotriosyl backbone. The substituents are 4-O-me-glucuronosyl residue (a), hexenuronosyl residue (b), 4-O-me-glucuronamide residue (c) and hexenuronamide residue (d). [M], molecular weight of the molecule; [M + 2AA], molecular weight of the molecule after labelling by 2-aminobenzoic acid, detected by MS in negative mode
