31P and 2H solid-state NMR studies of dry trehalose (TRE) and 1,2-dipalmitoyl-sn-phosphatidylcholine (DPPC) mixtures are reported. 31P spectra are consistent with a rigid head group above and below the calorimetric phase transition for both dry DPPC and a dry 2:1 TRE/DPPC mixture. In addition, 2H spectra of DPPC labeled at the 7-position of the sn-2 chain (2[7,7-2H2]DPPC) show exchange-narrowed line shapes with a width of 120 kHz over the temperature range 25-75 degrees C. These line shapes can… CONTINUE READING
