摘要
The three-dimensional structures of surfactant-like peptides containing 4–10 glycines as the components of the hydrophobic tails and aspartic acids as the hydrophilic heads (G4D2, G6D2, G8D2, G10D2) are investigated by using the multicanonical simulation procedure. The thermodynamically most stable low energy structures of the sequences are determined. Ramachandran plots are prepared and analyzed to predict the secondary structure motifs of the molecules.
