Conformations of Protected Oligo(y -methyl-L-glutamates) at the Air-Water Interface

Synopsis

In a previous paper dealing with the synthesis and the conformational behavior of a series of oligo(y-methyl-L-glutamates), it was shown that an organized conformation appeared a t approximately the heptapeptide level, the peptides being either dissolved in trifluoroethanol or spread a t the air-water interface.

The results were confirmed in the present work using the tritium-hydrogen exchange method and surface viscoelasticity measurements. The results suggest a conformational transition when the degree of polymerization of the spread peptides varies from six to eight.

Detailed insight can be obtained from proteins at and near the air-water interface using external reflection IR and circular dichroism techniques. Besides information on local protein concentrations and surface layer thickness, it is shown that beta-lactoglobulin displays a limited unfolding at the

## Abstract __The enzymatic hydrolysis of an L‐dipalmitoylphosphatidylcholine (L‐DPPC) monolayer at the air/water interface, catalyzed by phospholipase A__~__2__~ __(PLA__~__2__~__), serves as a model for biospecific interfacial reactions. The cleavage of L‐DPPC was investigated by Brewster angle m
