From: Identification of key regions and residues controlling Aβ folding and assembly

Locations of single D-amino acid substitutions in Aβ40 and Aβ42. Each position in which a single D-amino acid substitution was made is indicated by bolded, underlined, lower-case letters. Thirteen Aβ40 peptides and 24 Aβ42 peptides were studied.
