I-Microcrystalline Cellulose (MCC) |9004-34-6
Incazelo Yemikhiqizo
I-Microcrystalline cellulose igama le-pulp yokhuni elicwengekile futhi isetshenziswa njenge-texturizer, i-anti-caking agent, indawo yamafutha, i-emulsifier, i-extender, kanye ne-bulking ejenti ekukhiqizeni ukudla.Ifomu elivame kakhulu lisetshenziselwa izithasiselo zamavithamini noma amaphilisi.Ibuye isetshenziswe ekuhlolweni kwama-plaque ukubala amagciwane, njengenye indlela ye-carboxymethylcellulose.Ngezindlela eziningi, i-cellulose yenza i-excipient efanelekile.I-polymer eyenzeka ngokwemvelo, yakhiwe amayunithi e-glucose axhunywe nge-1-4 beta glycosidic bond.Lawa maketango aqondile we-cellulose ahlanganiswe ndawonye njenge-microfibril ehlanganiswe ndawonye ezindongeni zeseli lesitshalo.I-microfibril ngayinye ibonisa izinga eliphezulu lokubopha kwangaphakathi kwezinhlangothi ezintathu okuholela esakhiweni sekristalu esingancibiliki emanzini futhi simelana nama-reagents.Kukhona, nokho, izingxenye ezibuthakathaka ngokuqhathaniswa ze-microfibril ezinokuhlangana okubuthakathaka kwangaphakathi.Lezi zibizwa ngokuthi izifunda ze-amorphous kodwa zibizwa ngokunembe kakhulu ngokuthi i-dislocation kusukela i-microfibril iqukethe isakhiwo sesigaba esisodwa.Isifunda se-crystalline sihlukaniswe ukukhiqiza i-microcrystalline cellulose.
