Enzymatic hydrolysis of xyloglucan yielded a series of well-defined, highly branched oligosaccharides that, following reductive amination, were readily conjugated with fatty acids bearing C-8 to C-18 chains under mild conditions. The critical micelle concentration, determined by tensiometry and dye-inclusion measurements, showed a typical dependence on acyl chain length and was sensitive to the degree of galactosylation of the head group. Several compounds from this new group of surfactants, especially those with C-14 and C-16 chains, were useful for the extraction of membrane-bound enzyme markers from different plant cell compartments in catalytically active form.}, issn = {0959-6658}, doi = {10.1093/glycob/cwi013}, author = {Greffe, L and Bessueille, L and Bulone, V and Brumer, H} }
