title: Synthesis, preliminary characterization, and application of novel surfactants from highly branched xyloglucan oligosaccharides.
abstract: A novel class of nonionic, carbohydrate-based surfactants has been synthesized from the plant polysaccharide xyloglucan. Enzymatic hydrolysis of xyloglucan yielded a series of well-defined, highly branched oligosaccharides that, following reductive amination, were readily conjugated with fatty acids bearing C8 to C18 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 C14 and C16 chains, were useful for the extraction of membrane-bound enzyme markers from different plant cell compartments in catalytically active form.
