The 1H NMR spectra of t-BuSH and t-Bu2S2 under CO2 (Fig. 4a,b, and Supplementary Fig. 14) showed singlets at 1.38 and 1.29 ppm, respectively. On the other hand, we found that the new signals emerged at 0.88, 0.89, and 1.19 ppm in the 1H NMR spectrum of a THF-d8 solution...
While simple multilamellar dispersions of peptide/lipid mixtures or reconstituted protein/lipid mixtures are readily amenable to study by NMR, the presence of all orientations can complicate the analysis of the powder pattern NMR spectra obtained [18]. Mixtures of long and short chain lipids, such...
In the 1H NMR spectrum (Table 1), one methyl group (δH 1.32, s, H3-16), one N-methyl (δH 2.52, s, N-CH3), and one oxymethine proton (δH 2.95, br s, H-14) were observed. The 13C NMR and DEPT spectra ( Conflict of interest The authors declare that there is no ...
