Chitosan-Oligosaccharides (Chitoorigosaccharides) (1)

Chitosan-oligosaccharides are oligosaccharides which have the structure that D-glucosamines are bonded by beta-1,4 bonding and physiologically acitive. From dimer to hexamer of chitosan-oligosaccharide are separated using Asahipak NH2P-50 4E, a column for sugar analysis and evaporative light scattering detector (ELSD).
