Methylcellulose bụ ihe dị iche iche na-agbanwe agbanwe nke nwere ngwa na ụlọ ọrụ dị iche iche n'ihi ihe pụrụ iche ya. Mwepụta polysaccharide a sitere na cellulose bụ ihe a ma ama maka ike ya ịrụ ọrụ dị iche iche na mpaghara dị iche iche.
Njirimara chemical nke methylcellulose:
Methylcellulose na-arụ ọrụ site na etherification nke cellulose, polymer eke dị na mgbidi cell osisi. Ihe mejupụtara cellulose bụ nkeji glucose jikọtara ya na njikọ β-1,4-glycosidic. Usoro etherification gụnyere iji dochie otu hydroxyl na nhazi cellulose na otu methyl. Mgbanwe nke kemịkalụ a na-enye methylcellulose ihe na-esi na ya pụta ihe pụrụ iche, na-eme ka ọ na-agbaze na mmiri n'okpuru ọnọdụ ụfọdụ.
