Summary:"The oligosaccharide units of xyloglucans from the fruit cell walls of strawberry, persimmon, prune and banana were analyzed by enzymatic digestion followed by high-performance anionexchange chromatography with pulsed amperometric detection (HPAEC-PAD). The oligosaccharide units of the polysaccharides were XXXG, XXLG, XLXG, XXFG, XLLG and XLFG [where each (1-->4)-beta-linked D-glucosyl residue in the backbone is given a one-letter code according to its substituents: G, beta-D-Glc; X, alpha-D-Xyl-(l-->6)-beta-D-Glc; L, beta-D-Gal-(1-->2)-alpha-D-Xyl-(l-->6)-beta-D-Glc; F, alpha-L-Fuc-(1-->2)-beta-D-Gal-(1-->2)-alpha-D-Xyl-(1-->6)-beta-D-Glc] in an approximate molar ratio of 31:4:9:38:5:13 for strawberry, of 26:12:7:6:39:10 for persimmon, of 31:16:10:21:6:16 for prune and of 38:4:16:9:28:5 for banana. The ratios of the six oligosaccharide units are different among them. However, the xyloglucans of the cell walls of these fruits are considered to be similar to each other in basic structure."
