Sodium alginate (Na-Alg) is water-soluble, neutral, and linear polysaccharide. It the derivative of alginic acid which comprises 1,4-?-d-mannuronic (M) ?-l-guluronic (G) acids has chemical formula (NaC6H7O6). shows non-toxic, biocompatible, biodegradable, non-immunogenic properties. had been used for various biomedical applications, among most promising are drug delivery, gene wound dressing, h...

In 1917 Dochez and Avery (1) isolated from cultures of actively growing pneumococci and from the blood and urine of patients suffering from pneumonia a soluble substance which possessed the property of precipitating homologous antibody. Finding that this "specific soluble substance" neutralized the protective action of antipneumococcal immune bodies, Cole (2), in the same year, advanced an impo...

water soluble amphoteric graft copolymers of polysaccharide were synthesized via grafting of cationic monomer onto the sodium carboxymethylcellulose ()cmc)( and then used as a shale stabilizer in the water-based drilling fluids. accordingly, five types of cmc-graft copolymers with different ratios of acrylamide am)( and diallyldimethylammonium chloride dadmac)( were synthesized. grafting of mon...

abstract a large number of studies have shown that direct application of rock phosphate dose do not have enough efficiency to release phosphorus compared to chemical fertilizers. the main purpose of this study was to increase the efficiency of direct application of rock phosphate. incorporation of rock phosphate with sulfur, organic matter and inoculation with sulfur-oxidizing bacteria and phos...

In the present study, we investigated the anti-inflammatory activity of water-soluble polysaccharide of Agaricus blazei Murill (WSP-AbM) on ovariectomized osteopenic rats. The rats were administered orally WSP-AbM (200 mg/kg BW) for 8 weeks. Subsequent serum maleic dialdehyde (MDA) level, total antioxidant status (TAOS), nuclear factor kappa B (NF- κ B) level, polymorphonuclear (PMN) cells leve...

Pappagianis, D. (University of California, Berkeley), E. W. Putman, and G. S. Kobayashi. Polysaccharide of Coccidioides immitis. J. Bacteriol. 82:714-723. 1961.-Soluble polysaccharide from mycelia or culture filtrates of Coccidioides immitis was found to consist mainly of mannose, but also included small quantities of galactose and another reducing sugar. Isolation of the polysaccharide by etha...

A polysaccharide was found to be covalently linked to the peptidoglycan of the unicellular cyanobacterium Synechocystis sp. strain PCC6714 via phosphodiester bonds. It could be cleaved from the peptidoglycan-polysaccharide (PG-PS) complex by hydrofluoric acid (HF) treatment in the cold (48% HF, 0 degrees C, 48 h) yielding a pure, HF-insoluble peptidoglycan fraction and an HF-soluble polysacchar...

An edible fungal polysaccharide termed as ABP was obtained by extraction with hot water, and followed successive chromatographic purification using DEAE-Sepharose Fast Flow column and Sephacryl S-300 High-Resolution column. A symmetrical peak was obtained on high-performance size-exclusion chromatography with an average molecular weight of 5.17 × 104 Da, which was named ABP, and its main compon...

A new water-soluble polysaccharide (longan polysaccharide 1 (LP1)) was extracted and successfully purified from Dimocarpus longan pulp via diethylaminoethyl (DEAE)-cellulose anion-exchange and Sephacryl S-300 HR gel chromatography. The chemical structure was determined using Infrared (IR), gas chromatography (GC) and nuclear magnetic resonance (NMR) analysis. The results indicated that the mole...

The solubility of acid soluble soy protein (ASSP) is poor in the pH range of 4-7. ASSP-dextran conjugates were prepared through the Maillard reaction to increase the solubility and/or dispersibility of ASSP. By using the conjugates and ultrasonication emulsification, stable oil-in-water emulsions with submicrometer-sized droplets were obtained. The factors, such as ASSP conjugation degree, that...
