title: Sonication induced sheet formation at the air-water interface.
abstract: A hydrophobic pentadecapeptide, AGAAAA-GAVVGGLGG (1), part of the prion sequence PrP (106-127), on fresh aqueous dissolution takes a mixture of random and sheet conformations which forms a stable monolayer with a high beta-sheet content when compressed at the air-water interface. This also develops into a kinetically stabilized beta-sheet structure on sonication.
