WebHFIP could not induce α-helical conformation in Aβ16–22, and rings were obtained from freshly dissolved peptide. The rings formed by Aβ40, 42, 43, and Aβ16–22 are composed of the peptides in β-conformation and cause enhancement in thioflavin T fluorescence, suggesting that the molecular architecture of these structures is amyloid-like. Webpeptides are generated from amyloid precursor protein as a result of sequential b-secretase and g-secretase proteolytic activity (De Strooper et al.,1998 ;Vassar 1999 Wolfe et al., 1999). Imprecise cleavage specificity by g-secretase results in the generation of a range of Ab peptides varying in C-terminal length from 37 up to 46 amino acids ...
