Abstract

Differential Scanning Calorimetry studies of a synthetic peptide revealed the peptide decreased the temperature of the lamellar-hexagonal phase transition of cis-trans mixtures of phosphatidylethanolamine. The transition enthalpy varied significantly with lipid composition. The findings are discussed with reference to peptide saturation on the bilayer surface, bilayer thinning and peptide orientation.
