An gano cutar ta Alzheimer a matsayin cutar da ba ta dace ba ta furotin (proteopathy), wanda ya haifar da tarin plaque na furotin amyloid beta da furotin tau a cikin kwakwalwa. Wadannan plaques an yi su ne da kananan peptides, 39<unk>43 amino acid a tsawon, da ake kira amyloid beta (Aβ). Aβ wani yanki ne daga babban furotin amyloid precursor protein (APP). APP shine furotin na transmembrane wanda ya shiga cikin membrane na neuron. APP yana da mahimmanci ga haɓakar neuron, rayuwa, da gyaran bayan rauni. A cikin cutar Alzheimer, gamma secretase da beta secretase suna aiki tare a cikin tsarin proteolytic wanda APP ya rabu zuwa ƙananan ƙananan. Ɗaya daga cikin waɗannan ɓangarorin yana haifar da haɗarin ƙwayoyin beta amyloid, wanda ke haifar da haɗarin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayoyin ƙwayo
furotin mai alaƙa da microtubule
