Figure 5.
Molecular dynamics of SC components using DP (gray), CP (blue), and INEPT (red) pulse sequences for signal enhancement of molecular segments in either rigid (CP) or mobile (INEPT) microenvironments. 13C spectra of SC equilibrated in solutions with aw = 0.826 (the peak marked with a dot is from PEG) (A) and aw = 0.992 (B). Resonance lines from SC lipids and amino acid residues of the SC proteins are labeled in B. The intensity is scaled to give an equal DP signal of the peak centered around 32.8 ppm due to the different amounts of SC sample in each experiment.
