Analysis of plasma lipids by NMR spectroscopy: application to modifications induced by malignant tumors
Lipid extracts of plasma were studied by 31P and 1H NMR spectroscopy at 9.4 T.Signals recorded on lipid mixtures were assigned to different lipid classes using a data base built with two-dimensional 1H COSY spectra of seven standard lipids.Signals unique to glycerophospholipids, sphingolipids, and triacylglycerols were identified.31P and 1H NMR spe
