The pathological hallmark of Alzheimer's disease is cerebral accumulations of plaques, consisting of self-aggregated amyloid beta peptides. <i>Homo sapiens</i> and <i>H. glaber</i> amyloid beta peptides are different in only one amino acid. Herein, computational structural analyses were carried out to determine whether plaque development in <i>H. glaber</i> is prevented by the replacement of His13 with Arg13 in the amyloid beta peptide. AlphaFold2 was used to predict the structure of the <i>H. glaber</i> amyloid beta peptide. HADDOCK and Hex were used to self-dock the peptides and dock ions on peptides, respectively. Illustrations were made by PyMol and ChimeraX. Using VMD, we calculated the radius of gyration. The phylogenetic analysis was conducted by Mega. The results showed an accurate structure with two alpha helices separated by a short coil for <i>H. glaber</i>. Self-docking of the two amyloid beta peptides demonstrated a globular conformation in the <i>H. glaber</i> dimer, implying the unlikeliness of amyloid beta peptides' self-aggregation to form fibrillar structures. This conformational state resulted in lower electrostatic energy compared to <i>H. sapiens</i>, contributing to <i>H. glaber's</i> lower tendency for fibril and, ultimately, plaque formation. Phylogenetic analysis confirmed that amyloid precursor protein is highly conserved in each taxon of rodentia and primata.
