## Abstract Sodium dodecylsulfate (SDS) and dodecylphosphocholine (DPC) micelles are often used to mimic the membraneโ or receptorโbound states of peptides in NMR studies. From the present examination of a 26โresidue analog of exendinโ4 (TrEX4) by NMR and CD in water, aqueous 30% trifluoroethanol (

โฆ Synopsis
The effects of micelles of cetyltrimethylammonium bromide (CTAB) and cetylpyridinium bromide (CPB) on the observed pseudo-first-order rate constants for the interaction of ninhydrin with tryptophan were studied. The influence of different parameters was considered, i.e., reactant concentration, surfactant concentration, temperature, and effect of added salts. The data are explained in terms of the pseudo-phase model of the micelles. Copyright 1999 Academic Press.
