Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Mapuroteni anogona kukamurwa zvisina kurongwa kuva mapoka makuru matatu, ayo anowirirana nezvimiro zvepamusoro: mapuroteni eglobular, mapuroteni ane fibrous, uye mapuroteni emadziro. Anenge mapuroteni ose ane mabhora anogadziriswa uye mazhinji acho maenzymes. Mapuroteni ane fibrous anowanzova akaumbwa, akadai se collagen, chinhu chikuru chinoumba nyama inobatanidza, kana kuti keratin, chinhu chinogadzira mapuroteni ebvudzi nezvipikiri. Mapuroteni e membrane anowanzoshanda semagamuchiri kana kupa nzira dzema molecule ane polar kana ane charged kuti apfuure nepakati pemembrane yesero. Mhosva chaiyo ye intramolecular hydrogen bonds mukati memapuroteni, isina kudzivirirwa zvakanaka kubva pakurwiswa nemvura uye nokudaro inosimudzira kupera kwavo mvura, inonzi dehydrons.  Mubvunzo: Imhandoi yamapuroteni inowanzova inonyungudika nguva dzose?
