Inside the body, some seemingly harmless proteins have sinister potential. In the case of Alzheimer’s disease, the amyloid-beta (Aβ) protein, which is vital for brain growth, can become tainted and destroy cells, which leads to forgetfulness and memory loss. Proteins are neat little things that can only perform their functions if folded properly. Thus, the misfolding and deposition of amyloid beta in the brain is the main hallmark of Alzheimer’s disease.
