Abstract

We examined the effects of air-water and water-sevoflurane interfaces on conformational properties of amyloid- β peptide (ABP). Fractions were extracted from sub-interfacial (air-water) and supra-interfacial (water-sevoflurane) layers and compared with aqueous bulk layers using fluorescence properties of ABP provided by a single tyrosine. The observations suggest that interfacial ABP may be more disordered than bulk ABP.
