This work explores the synthesis, development and application of [1,4-13C]-diethylsuccinate ([13C]-DES) via DNP polarization. These studies provide a reassignment of the metabolites observed in previous reports and a reexamination of the role of the TCA cycle in processing [13C]-labeled diethylsuccinate probes.
