Ozonolysis for selectively depolymerizing polysaccharides containing -D-aldosidic linkages

Screening of Mushrooms for Polysaccharides

Background: Mushrooms have been valued as high tasty nutritional and nutraceutical food throughout the world. At present 270 species of mushrooms are known to have various nutritional and therapeutic properties. Polysaccharides are the primary content of mushrooms that are used for their pharmaceutical properties as immunostimulators. Objectives: Here, Mushrooms were screened for useful polysa...

Conformations of Uronic Acid Containing Polysaccharides

Analyses of X-ray diffraction patterns obtained from ordered specimens of a variety of polyuronides have provided the opportunity to examine their molecular geometry in the condensed phase. A brief review is given of the simpler homopolysaccharide components of alginic acid, followed by the connective tissue polydisaccharides: hyaluronic acid, the chondroitin suiphates, dermatan sulphate, hepar...

Biofunctional Composites of Polysaccharides Containing Inorganic Nanoparticles

Hydrogels Containing Marine Polysaccharides For Bone and Cartilage Tissue Engineering

Introduction: The most common biopolymers used to build-up 3D scaffolds for bone and cartilage tissue engineering are chitosan, alginate, cellulose derivatives, hyaluronic acid, chondroitin sulfate, collagen and gelatin. In this study, we propose to evaluate the potential of two new marine exopolysaccharides (HE800 and GY785) that are glycosaminoglycan-like polymers and that can be produced in ...

Surfactant protein D binds selectively to Klebsiella pneumoniae lipopolysaccharides containing mannose-rich O-antigens.

Surfactant protein D (SP-D) plays important roles in the regulation of innate immune responses in the lung. We have previously shown that SP-D can agglutinate and enhance the macrophage-dependent killing of specific unencapsulated phase variants of Klebsiella pneumoniae. In the present studies, we used 16 clinical isolates of Klebsiella representing four O-serotypes and examined the interaction...
