13C isotopomics of triacylglycerols using NMR with polarization transfer techniques†
Abstract
A rapid and very precise method is proposed to simultaneously determine the position-specific 13C content and the metabolomic profile of triacylglycerols (isotopomics). 13C-NMR spectra are obtained by using an adiabatic INEPT sequence; the experiment time is reduced by a factor of 7 with respect to a one-pulse acquisition.
