Cellulose bụ polima a na-emegharịgharị nke ukwuu n'ụwa yana akụkụ bụ isi nke mgbidi sel osisi.N'ime osisi vaskụla, a na-eme ka njikọ cellulose site na nnukwu, plasma membrane-localized cellulose synthase complex (CSC), nke a na-ahụ anya dị ka usoro hexameric rosette.A chọrọ isoforms atọ pụrụ iche cellulose synthase (CESA) maka mgbakọ na ọrụ CSC.Agbanyeghị, nkọwapụta nke ọnụọgụ ma ọ bụ stoichiometry nke CESA dị n'ime CSC ka bụ ihe a na-apụghị ịgbagha agbagha.N'ime ọmụmụ ihe a, anyị na-egosi 1: 1: 1 stoichiometry n'etiti atọ Arabidopsis thaliana secondary cell isozymes: CESA4, CESA7, na CESA8.Ekpebiri oke a site na iji usoro dị mfe mana mara mma nke ọnụọgụ immunoblotting site na iji ọgwụ mgbochi isoform na (35) ụkpụrụ protein akpọrọ maka CESA ọ bụla.Na mgbakwunye, ahụrụ stoichiometry equimolar a hụrụ ka edobere n'akụkụ axis nke stem ahụ, nke na-anọchi anya gradient mmepe.Nsonaazụ anyị na-emeju nyocha spectroscopic na nso nso a na-atụ aka na microfibril cellulose nwere yinye 18.N'ịchịkọta ọnụ, anyị na-atụ aro na CSC bụ hexamer nke CESA trimers na-arụsi ọrụ ike, yana CESA nke ọ bụla n'ogo nha nha.Nchọpụta a bụ ọganihu dị oke mkpa n'ịghọta ka CESA si ejikọta ọnụ iji mepụta ogige dị elu, nke bụ isi ihe na-achọpụta microfibril cellulose na ihe mgbidi cell.
