Abstract

The tetrapeptide derivative Boc-Ile-Gly-Met-Thr(Bzl)-OBzl 1 forms micellar aggregates in chloroform. Evidence for micelle formation in chloroform has been obtained by IR, Raman scattering, fluorescence spectroscopic methods and calcium picrate extraction techniques. The thermodynamic data indicate that the driving force for the micellisation is enthalpic in nature.
