Conclusion
Chitin, isolated from fish scales of Labeo rohita, was
successfully converted into chitosan by deacetylation
reaction. The prepared chitosan was utilised to prepare
carboxymethyl chitosan, a hydropilic biomaterial.
Industries and pharmaceutical companies may develop
and widely utilize many other useful products by using
the chitin and chitosan from fish scales of Labeo rohita
which is being thrown as waste.
