title: A 13C NMR study of the application of [U-13C]succinate for metabolic investigations in rabbit renal proximal convoluted tubular cells.
abstract: The fate of the 13C label arising from [U-13C]succinate in rabbit renal proximal convoluted tubular (PCT) cells, incubated with [U-13C]succinate, was investigated by 13C NMR spectroscopy of the perchloric acid extracts of the cell pellets. The 13C label of [U-13C]succinate was predominantly metabolized into glutamate, glutamine, and into glucose, lactate, and alanine, which is the consequence of a carbon efflux of the label from the Krebs cycle at the stage of alpha-ketoglutarate and oxaloacetate, respectively.
