Kedu ihe bụ Chitosan?
Chitosan (chitosan), nke a makwaara dị ka chitin deacetylated, na-enweta site na deacetylation nke chitin, nke dị n'ọtụtụ ebe na okike. Aha kemịkalụ bụ polyglucosamine (1-4) -2-amino-BD glucose.
Chitosan bụ ihe dị mkpa sitere n'okike nke a na-ejikarị na ọgwụ, nri, ọrụ ugbo na mpaghara ndị ọzọ. Enwere isi mmalite chitosan abụọ: shrimp na nshịkọ mmịpụta na isi ero. Usoro nke nchacha chitosan gụnyere decalcification, deproteinization, chitin, na deacylation, na n'ikpeazụ a na-enweta chitosan. Usoro ndị a na-eme ka mwepụta chitosan dị elu site na shrimp na nshịkọ.
Njirimara na akụrụngwa nke chitosan na-eme ka a na-eji ya eme ihe n'ọtụtụ ebe dị iche iche. N'ihi ọdịdị amino na cationic nke molecule ya, chitosan nwere ọtụtụ ihe dị mkpa:
1.Biocompatibility: Chitosan nwere ezigbo bioacompatibility maka ụmụ mmadụ na anụmanụ, ọ dịkwa mma maka usoro nnyefe ọgwụ, biomaterials na ngwa ndị ọzọ na ngalaba ahụike.
Nhazi 2.Gel: N'okpuru ọnọdụ acidic, chitosan nwere ike ịmepụta gels ma jiri ya mee ihe na-emepụta ihe, nkà na ụzụ anụ ahụ, na usoro nnyefe ọgwụ.
3.Antibacterial Properties: Chitosan na-egosipụta ọrụ antibacterial megide nje bacteria na fungi ma nwee ike iji ya na ihe ndị na-egbu egbu, nkwakọ nri na akụrụngwa ọgwụ.
4.Moisturizing Njirimara: Chitosan nwere ezigbo ihe na-edozi ahụ ma nwee ike iji ya na ihe ịchọ mma na ngwaahịa nlekọta anụ ahụ.
