What are Oligosaccharides & Polysaccharides?
Oligosaccharides are carbohydrates, composed of up to twenty monosaccharides linked by glycosydic bonds, widely used in food and pharmaceutical industries. These compounds can be obtained by extraction from natural sources (milk, vegetables, fruits), and by chemical or biotechnological processes. In the last case, chemical structures and composition of the generated oligosaccharides depend on the type and source of enzymes, and on process conditions, including the initial concentration of substrate. These are the basic requirements to consider for Oligosaccharides & Polysaccharides Services.
What is the significance of Bioactive Oligosaccharides & Polysaccharides in API development?
Plant cell wall polysaccharide composition varies substantially between species, organs and genotypes. Knowledge of the structure and composition of these polysaccharides, accompanied by a suite of well characterized glycosyl hydrolases will be important for the success of lignocellulose biofuels. Current methods used to characterize enzymatically released plant oligosaccharides are relatively slow. A method and software was developed allowing the use of a DNA sequencer to profile oligosaccharides APIs derived from plant cell wall polysaccharides (DNA sequencer-Assisted Saccharide analysis in High throughput, DASH). A new device installed at oligosaccharides & polysaccharides API development service providers which can analyses 96 samples simultaneously by capillary electrophoresis can be used to separate fluorophore derived reducing mono- and oligosaccharides from plant cell walls. Using electrophoresis mobility markers, oligosaccharide mobilities were standardized between experiments to enable reproducible oligosaccharide identification.
These mobility markers can be flexibly designed to span the mobilities of Oligosaccharides APIs development under investigation, and they have a fluorescence emission that is distinct from that of the saccharide labelling. Methods for relative and absolute quantitation of oligosaccharides are described. Analysis of a large number of samples is facilitated by the software which was developed in parallel. Use of this method was exemplified by comparing xylan structure and content in Arabidopsis thaliana mutants affected in xylan synthesis. The product profiles of specific xylanases were also compared in order to identify enzymes with unusual oligosaccharide products.

Synthesis Strategies for Polysaccharides in Oral Drug Delivery
It is well known that oligosaccharides can be formed from monosaccharides by the action of mineral acids (chemical synthesis). This process, known as “reversion,” explains the production of oligosaccharides during acidic hydrolysis of lactose. The Oral drug delivery conditions suitable for oligosaccharide production during acidic hydrolysis of lactose and the resulting oligosaccharide structures formed have been well studied. It was reported that there is formation of a complex mixture of disaccharides and trisaccharides, with a variety of linkages with ?? and ??anomeric configurations in Organized polysaccharide fibers, and anhydro?sugars, as a result of this chemical process. Probably due to the lack of product specificity and extreme conditions applied during acidic hydrolysis of lactose, this GOS production process is not used on a large scale.
