| 1 | Like most worms, helminths synthesize chitin for their pharynx. | |
| 2 | But chitin deposits never build up on the sea or forest floor. | |
| 3 | In this paper a semi-dry method with microwave treatment is described for the deacetylation of chitin to obtain chitosan. | |
| 4 | In this paper, advances in the application and research of chitin deacetylase in preparation of chitosan are summarized. | |
| 5 | While humans and other vertebrates do not produce chitin, our bodies are equipped to recognize and eliminate it. |
