Cellulose:
Cellulose wani sinadari ne mai yawan sinadarin polysaccharide wanda ya ƙunshi glucose kuma shine babban sinadari na bangon ƙwayoyin shuka. A zafin jiki na ɗaki, cellulose ba ya narkewa a cikin ruwa ko kuma a cikin sinadarai na halitta. Yawan sinadarin cellulose na auduga yana kusa da kashi 100%, wanda hakan ya sa ya zama mafi tsaftar tushen cellulose na halitta. Gabaɗaya, cellulose yana da kashi 40-50%, kuma akwai kashi 10-30% na hemicellulose da kashi 20-30% na lignin.
Bambanci tsakanin cellulose (dama) da sitaci (hagu):
Gabaɗaya dai, sitaci da cellulose polysaccharides ne na macromolecular, kuma ana iya bayyana tsarin kwayoyin halitta a matsayin (C6H10O5) n. Nauyin kwayoyin halitta na cellulose ya fi na sitaci girma, kuma ana iya raba cellulose don samar da sitaci. Cellulose shine D-glucose da β-1,4 glycoside Macromolecular polysaccharides waɗanda suka ƙunshi haɗin gwiwa, yayin da sitaci ke samar da haɗin gwiwa na α-1,4 glycoside. Cellulose ba shi da reshe, amma sitaci yana da reshe na glycosidic bonds 1,6. Cellulose ba shi da kyau narkewa a cikin ruwa, yayin da sitaci yana narkewa a cikin ruwan zafi. Cellulose ba shi da tausayi ga amylase kuma baya canzawa zuwa shuɗi lokacin da aka fallasa shi ga iodine.
Cellulose Ether:
Sunan Ingilishi nacellulose ethershine cellulose ether, wanda wani sinadari ne na polymer wanda ke da tsarin ether da aka yi da cellulose. Yana da samfurin amsawar sinadarai na cellulose (shuka) tare da wakilin etherification. Dangane da rarrabuwar tsarin sinadarai na maye gurbin bayan etherification, ana iya raba shi zuwa anionic, cationic da nonionic ethers. Dangane da wakilin etherification da aka yi amfani da shi, akwai methyl cellulose, hydroxyethyl methyl cellulose, carboxymethyl cellulose, ethyl cellulose, benzyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, cyanoethyl cellulose, benzyl cyanoethyl cellulose, carboxymethyl hydroxyethyl cellulose da phenyl cellulose, da sauransu. A cikin masana'antar gini, ana kuma kiran cellulose ether cellulose, wanda shine sunan da ba daidai ba, kuma ana kiransa cellulose (ko ether) daidai.
Tsarin Kauri na Cellulose Ether Mai Kauri:
