In recent decades, three generations of thiomers have been developed with the main purpose obtaining enhanced interactions mucosal tissues. Therefore, many different types thiolated ligands generated and attached to polymeric backbones. The aim this study was synthesize all directly compare their properties regarding mucus penetration mucoadhesion. Starting from pectin, unprotected thiomer pect...

Cotton fibre is mainly composed of cellulose, although non-cellulosic polysaccharides play key roles during fibre development and are still present in the harvested fibre. This study aimed at determining the fate of non-cellulosic polysaccharides during cotton textile processing. We analyzed non-cellulosic cotton fibre polysaccharides during different steps of cotton textile processing using GC...

Atomic force microscopy (AFM) allows the analysis of individual polymers at nanostructural level with a minimal sample preparation. This technique has been used to analyse the pectin disassembly process during the ripening and postharvest storage of several fleshy fruits. In general, pectins analysed by AFM are usually visualized as isolated chains, unbranched or with a low number of branchs an...

INTRODUCTION Xylella fastidiosa (Xf) is a Gram-negative xylem-limited bacterium that causes Pierce’s disease (PD), plum leaf scald, almond leaf scorch, phony peach disease and many other diseases. For many plant species there is no resistant germplasm. Xylem vessels may be filled with exopolysaccharides produced by the bacterium, and pectins, gums and tyloses produced by the plant. There has be...

Commercial cellulase complexes produced by cellulolytic fungi contain enzyme activities that are capable of hydrolyzing non-cellulosic polysaccharides in biomass, primarily hemicellulose and pectins, in addition to cellulose. However, xylanase activities detected in most commercial enzyme preparations have been shown to be insufficient to completely hydrolyze xylan, resulting in high xylooligom...

Prebiotic oligosaccharides, with a degree of polymerization (DP) of mostly less than 10, exhibit diverse biological activities that contribute to human health. Currently available prebiotics are mostly derived from disaccharides and simple polysaccharides found in plants. Subtle differences in the structures of oligosaccharides can cause significant differences in their prebiotic proper-ties. T...

Levels of biologically active and reserve substances were investigated in the leaves rhizomes Paeonia anomala L., P. hybrida Pall., lactiflora Pall. The peonies’ are rich ascorbic acid (1205.7 mg/100g ) tannins (15.9% 15.7% at beginning growth season. Concentrations flavonols, pectins, carotenoids Siberian peonies low is a promising species for further research on set levels because this stands...
