ONE-DIMENSIONAL AND 2-DIMENSIONAL NMR-STUDIES OF PLASMALOGENS (ALK-1-ENYL-PHOSPHATIDYLETHANOLAMINE)

H-1 and C-13 nuclear magnetic resonance (NMR) spectra of phosphatidyle thanolamine plasmalogen were studied. Resonances in both spectra were assigned by conventional one- and two-dimensional NMR techniques. Dist inctive signals corresponding to the olefinic carbons near the vinyl e ther group were shown to be the most useful in both qualitative and qu antitative analysis. The plasmalogen content in different fish lipid s amples, as determined by C-13-NMR spectroscopy, was in good agreement with the data obtained by gas chromatography.
