Glucan oligosaccharides are obtained through hydrolysis of polysaccharides. Elicityl offers different oligosaccharides based on a core glucose repeating units:
- Cellodextrins (β1-4 linkage) are produced by acid hydrolysis of cotton. Under a degree of polymerization of 8-10, cellodextrin are water-soluble and short oligomers display potential prebiotic and health-promoting properties for animals (1).
- Maltodextrins (α1-4 linkage) are obtained by extraction and purification of Maltrin®. They are obtained with high purity assessed by HPLC analysis and can be used for analysis.
- Xyloglucans are small oligosaccharides extracted from leftovers of apple. Elicityl have developed the trademark product PEL101GV® corresponding to the extraction of one xyloglucan. These xyloglucans can be used as elicitor and biofertilizers.
Glucans are most abundant polysaccharides in nature. They are linear or ramified polysaccharides composed of glucose repeating units linked by glycosidic bond of various configuration. The most known is cellulose, a polymer composed of β(1-4)Glucose repeating units which forms the primary cell wall of green plants. Others well known polysaccharides are amylose and amylopectin which are used by plants as a source of energy storage, and glycogen which is used by animals as energy storage.
