Description

Chitosan Oligomer is high purity low molecular weight Chitosan oligosaccharide. It is soluble in dilute aqueous acid and is also reasonably soluble in water. The degree of deacetylation (DDA) is above 90%. Chitosan was prepared from crab shell.

Properties

Chitosan is produced by deacetylation  of  chitin, which is the structural  element  in the  exoskeleton  of  crustaceans  (such as crabs and shrimp) and cell walls of  fungi. The degree of deacetylation (%DD) can be determined by  NMR spectroscopy from 60 to 100%.Chitosan products are characterized by either its MW or its viscosity.  The  amino  group in chitosan has a  pKa  value of ~6.5.
