摘要
Structures of the micelles which are formed by the chiral oligopeptide surfactant N-dodecanoyl-L-proline tripeptide anions have been examined using small-angle neutron scattering spectral analysis. Results show that the chiral N-dodecanoyl-L-proline trimeric anions may form a spherical micelle with an aggregation number of 36 and that the oligopeptide portions with a poly-L-proline I-type helical structure are saturated with water.
