We discuss a simple modification of the well-known method of giant vesicle electroformation that allows for a direct addition of water-soluble species to the phospholipid bilayers. Using this modified method, we prepare phospholipid vesicles decorated with chitosan, a water-soluble polysaccharide currently investigated for potential pharmacological applications. We find that the method allows t...

In a previous investigation conducted in this laboratory (1) a starch polysaccharide, apparently identical with the watersoluble component of the common cereal and tuber starches, was isolated from the woody tissue of the apple tree (Malus malus). Thus it appears that starches of widely different origin may contain a common water-soluble polysaccharide. Through an application of the method (2) ...

Extracts of defatted cocoa inhibited the biosynthesis of extracellular polysaccharide by both cell-free and cell-associated streptococcal glucosyltransferases, but did not affect growth or acid production. Both water-insoluble and water-soluble polysaccharide syntheses were inhibited, and the net result was a shift away from adherence-supportive polysaccharide. Inhibition was non-competitive wi...

A water-soluble and neutral polysaccharide was extracted from the current pseudobulbs of Oncidium "Gower Ramsey" during the early inflorescence stage (flower stalk less than 4 cm) by hot water, precipitated with ethanol, and purified with an anion exchanger. From the data of monosaccharide composition and linkage and anomeric configuration analyses, the polysaccharide was identified as a linear...

The water-soluble polysaccharide (SCP) was isolated from Semen Coicis through hot water extraction followed by ethanol precipitation. The polysaccharide was deproteinized by using the Sevag reagent, and the polysaccharide was free of proteins as scan by UV Spectra in 260 nm and 280 nm. In order to evaluate its antioxidant activities, Free radicals scavenging activities on superoxide radicals, h...

A water-soluble polysaccharide (BEBP) was extracted from Boletus edulis Bull using hot water extraction followed by ethanol precipitation. The polysaccharide BEBP was further purified by chromatography on a DEAE-cellulose column, giving three major polysaccharide fractions termed BEBP-1, BEBP-2 and BEBP-3. In the next experiment, the average molecular weight (Mw), IR and monosaccharide composit...

Five soluble polysaccharide fractions were sequentially extracted with water, EDTA, Na2CO3, 4% KOH, and 14% KOH solutions at room temperature for 4 h from cell wall material of rabbiteye blueberry (Vaccinium ashei) fruits, and their physicochemical properties were examined. The sequential treatments yielded a total 36.02% soluble polysaccharides of the dry cell wall material. HPAEC and spectros...

The first atom transfer radical graft copolymerisation at ambient temperature in water from a soluble polysaccharide is demonstrated for a range of monomer types.
