Results Polysaccharide SP800301 extracted from Saposhnikoviae Radix had good homogeneity with a molecular weight of 9.1 x 104 g/mol. The uronic acid content was 52.72%. The monosaccharide group comprised rhamnose, galacturonic acid, glucose, galactose, and arabinose, ...
Despite its relevance as a disease-causing serotype, the associated capsular polysaccharide remains poorly characterized. We describe in this report the chemical structure of the K15 polysaccharide, based on chemical analysis and nuclear magnetic resonance (NMR) data. The repeating structure of the K...
The EPS and IPS of P. polycephalum microplasmodia had different chemical properties including carbohydrate, protein and total sulfate group contents, monosaccharide composition and molecular weights, which led to different cytotoxicity activities. The crude and partially purified IPSs would be potential mate...
Its chemical structure was characterized by monosaccharideanalysis, methylation analysis and analysis of its FT-IR, high performance gel permeationchromatography (HPGPC) and 1D/2D-NMR spectra data. The backbone of BP1 consists ofÑ 6 α - D -Glcp 1 Ñ 6,3 α - D -Glcp 1 Ñ ( 6 ...
of bacteria based on specific binding of their surface to a monosaccharide, mannose has been reported17, where a quartz crystal microbalance (QCM) with a mannose-modified electrode was used for the detection of mass change; however, the number of detectable bacterial species is limited. With ...
The synthesis of azo dyes. The Chemical Synthesis of Sugar Molecules The human body utilizes sugar molecules for energy. Glucose is a simple monosaccharide molecule that the body uses for energy. Disaccharide molecules, like sucrose, are produced through chemical synthesis through the dehydration of ...
polysaccharide in the recent years at home and abroad, this article explains the monosaccharide and chain structure of sugar in Astragalus polysaccharide, and the functions in the immune regulation, protection of the myocardium, decrease of blood sugar, senility postponement, and promotion of the ...
A homogeneous polysaccharide, named FMP2-1, was extracted from floral mushroom grown in the Huangshan Mountain and further purified by DEAE-cellulose and Sephacryl S-300 column chromatography. Monosaccharide analysis showed that FMP2-1 was glucan. The structural features of FMP2-1 were carried out...
In addition, a structural α-mannan model was suggested based on a nuclear magnetic resonance (NMR) analysis. 2. Material and methods 2.1. Materials Monosaccharide standards (d-glucose, d-galactose, d-fructose, l-rhamnose, d-mannose, d-arabinose, l-fucose, d-xylose, d-glucuronic acid), ...
In the future,more studies shall be made on the chemical structure,toxicology,clinical pharmacology of Rehmanniae Radix polysaccharides,in order to define their mechanisms and lay a foundation for promoting their clinical application and safety. 展开 关键词: Rehmanniae Radix polysaccharides chemistry ...
