Abstract
Abstract Xyloglucan oligosaccharides were enzymically released from purified cell walls isolated from suspension-cultured sycamore cells. The O -acetyl substitution pattern of these oligosaccharides was determined by 1 H NMR spectroscopy. This analysis revealed that most of the 2-linked galactosyl residues of the decasaccharide and nonasaccharide fragments of cell wall xyloglucan are O -acetyl substituted, while the heptasaccharide fragment does not contain O -acetyl substituents. This acetylation pattern does not differ significantly from that of the same xyloglucan oligosaccharides enzymically released from the xyloglucan secreted by suspension-cultured sycamore cells.
