摘要
Furanoid sugar amino acid based peptide and a dimer fold into pseudo P-turn-like structures in DMSO-d(6) with intramolecular H-bonds between LeuNH and sugarOH. In CDCl3, they display a repeating beta-turn-type secondary structure at lower concentrations and start to form aggregates that gradually turn into excellent organogels as the concentrations are increased, a phenomenon observed for the first time in sugar amino acid containing peptides.
