Gramicidin acyl chain conformation

An additional example for the usefulness of IR spectroscopy in studying drug interactions with phospholipid vesicles is the quantitative determination of acyl chain conformation in gramicidin-DPPC mixtures [63]. The technique provides a quantitative measure of the extent to which membrane-spanning peptides induce disorder of phospholipid gel phases and order in liquid crystalline phases. [Pg.78]

The quantitative determination of phospholipid acyl chain conformational disorder in hydrated systems of dipalmitoylphosphatidylcholine (DPPC), dipalmitoylphosphatidylethanolamlne (DPPE), mixtures containing DPPC and cholesterol, and mixtures of DPPC and Gramicidin D has been made using FT-IR. The... [Pg.24]
