Micellar structure of an oligopeptide surfactant "trimeric N-dodecanoyl-L-proline potassium salt" in aqueous solution - small-angle neutron scattering study

Structures of the micelles which are formed by the chiral oligopeptide surf actant N-dodecanoyl-L-proline tripeptide anions have been examined using sm all-angle neutron scattering spectral analysis. Results show that the chira l 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.
