Concept explainers
To explain: How chitin can be chemically modified.
Concept introduction:
Chitin is a structural polysaccharide and it is made up of glucose units. A natural biopolymer that is derived from chitin is known as chitosan. They are extracted from the shells of crabs, lobster and shrimp. The chitosan can block the absorption of cholesterol and dietary fat. It is also used for medicine.
To explain: The reason how the chitin modification treatment affects its physical and chemical properties.
