Chitin, uas tshwm sim hauv cov xwm txheej raws li kev txiav txim siab macrofibrils, yog qhov tseem ceeb ntawm cov txheej txheem nyob rau hauv lub exoskeletons ntawm crustaceans, crabs thiab cws, nrog rau cov phab ntsa ntawm tes ntawm fungi. Rau kev siv biomedical chitin feem ntau hloov mus rau nws cov deacetylated derivative, chitosan (1).
chitin pom hauv dab tsi?
Chitin yog lwm qhov ntau tshaj plaws polysaccharides hauv ntiaj teb, uas muaj dav nyob hauv exoskeleton ntawm cws, crabs, thiab kab nrog rau cov phab ntsa ntawm tes ntawm fungi thiab algae..
Puas muaj chitin hauv tib neeg?
Chitin yog cov khoom tsim ntawm arthropod exoskeletons, fungi cell phab ntsa, mollusk plhaub, thiab ntses nplai. Thaum tib neeg tsis tsim chitin, nws tau siv tshuaj thiab ua zaub mov ntxiv.
Puas chitin tsuas pom hauv cov nroj tsuag?
Chitin Cell Wall
Thaum cov phab ntsa cell tsis tsuas pom muaj nyob hauv cov nroj tsuag thiab cov fungi xwb, chitin tsuas yog siv rau hauv cov phab ntsa ntawm cov kab mob fungi. Lwm cov nroj tsuag muaj cov phab ntsa ntawm tes ua los ntawm cellulose, thiab cov kab mob phab ntsa ntawm tes yog tsim los ntawm peptidoglycan.
Puas yog chitin ib qho qauv?
Chitin yog loj, txheej txheem polysaccharide ua los ntawm cov saw hlau hloov kho cov piam thaj. Chitin muaj nyob rau hauv exoskeletons ntawm kab, cell phab ntsa ntawm fungi, thiab tej yam nyuaj qauv nyob rau hauv invertebrates thiab ntses. Hais txog kev nplua nuj, chitin yog thib ob rau tsuas yog cellulose xwb.
