Physical studies of phospholipids. IV. High resolution nuclear magnetic resonance spectra of phospholipids and related substances.
The nuclear magnetic resonance spectra of phosphatidylethanolamines, phosphatidylcholines, phosphatidylserines, and sphingomyelin are discussed in terms of molecular structure. The factors influencing the band width of the protons of the polar head of phosphatidylcholines are surveyed. It is found that the band widths vary with solvent and that this variation can perhaps be correlated with the ...
متن کاملTwo-dimensional nuclear magnetic resonance spectra of selected tricyclic antidepressants.
Two-dimensional nuclear magnetic resonance (2D NMR) spectroscopy has been used to assign 13C spectra of the tricyclic antidepressants imipramine and chlorimipramine . The 2DINADEQUATE method was used to unambiguously assign the aromatic spectral region for the former compound. Errors in previous literature assignments based on 1D methods were corrected. For chlorimipramine the pitfalls of class...
متن کاملNuclear magnetic resonance spectroscopy: 13C spectra of unsubstituted inositols.
The chemical shifts of (13)C in natural abundance have been obtained from nuclear magnetic resonance spectra of scyllo-, myo-, chiro-, and epi-inositols at 15.1 MHz. A set of empirical substitutent parameters were derived and shown to be moderately successful in correlating the (13)C resonance-line positions for these substances. The substituent parameters conform generally to the idea that ste...
متن کامل13C nuclear magnetic resonance spectra of fungal melanins.
The 13C resonance spectra of fungal melanins from Aspergillus niger, Eurotium echinolatum, and Stachybotrys chartarum are reported. The spectra were taken in 5% W/W solution of the substances in 0.1 N NaOD in D2O using the Fourier-transform-technique. The spectra and possible assignments of the bands are discussed. The similarities of these spectra to those of soil humic acids are unexpectedly ...
متن کاملNUCLEAR MAGNETIC RESONANCE STUDY OF THE STRUCTURE OF GLYOXALDIHYDRAZONE
Study of the nuclear magnetic resonance spectra of glyoxaldihydrazone in dimethylsulfoxide and deuterochlorofonn leads to the conclusion that this compound exists predominantly in non-chelate structure
