Abstract
Two regions of the IR spectrum of phospholipid molecules have been utilized to monitor acyl chain conformational order in model biomembranes of increasing complexity from one component systems to living cells. The rocking modes of CD2 groups synthetically incorporated into the acyl chains provide a measure of % gauche roamer formation as a function of chain position from the interfacial region to the bilayer center. In addition, the CH2 wagging vibrations in disordered phases provide a means of identifying the particular two- and three-bond conformational states that dominate the disordering process, while the band progressions that result from the wagging of coupled CH2 oscillators in ordered states monitor the fraction of all-trans conformations.
