Amorphous solid, specific rotation [α]D11-3° ~ +10°.
It is a rare natural cationic polyelectrolyte.
A polysaccharide obtained by hydrolysis of a strong base or enzymolysis to remove the acetyl group from the chitin glycogroup.
Can dissolve in low acidity aqueous solution, has good biocompatibility, no antigenicity, insoluble in human liquid.
