CD sub(2) rocking modes as quantitative infrared probes of one-, two-, and three-bond conformational disorder in dipalmitoyl-phosphatidylcholine and dipalmitoyl-phosphatidylcholine/cholesterol mixtures

CD sub(2) rocking modes as quantitative infrared probes of one-, two-, and three-bond conformational disorder in dipalmitoyl-phosphatidylcholine and dipalmitoyl-phosphatidylcholine/cholesterol mixtures

The use of CD sub(2) rocking modes in the IR spectrum as quantitative probes of phospholipid conformational disorder has recently been described for aqueous dispersions of 1,2-dipalmitoyl-phosphatidylcholine (DPPC) and DPPC/cholesterol mixtures. Initial studies focused at the 4, 6, and 10 acyl chain...

Zusammenfassung:The use of CD sub(2) rocking modes in the IR spectrum as quantitative probes of phospholipid conformational disorder has recently been described for aqueous dispersions of 1,2-dipalmitoyl-phosphatidylcholine (DPPC) and DPPC/cholesterol mixtures. Initial studies focused at the 4, 6, and 10 acyl chain positions of DPPC. In the current work, the method is extended to the 2, 3, 12, and 13 positions.
