[2,3‐ 13 C 2 ]glucose is a novel and specific tracer of the pentose phosphate pathway (PPP). 13 C NMR analysis of lactate after the administration of [2,3‐ 13 C 2 ]glucose informs PPP activity and glycolysis because [1,2‐ 13 C 2 ]lactate arises from glycolysis and [2,3‐ 13 C 2 ]lactate arises exclusively through the PPP. In rats receiving [2,3‐ 13 C 2 ]glucose, the PPP was more active in the fed versus fasted state in most organs. Both the PPP and glycolysis were substantially increased in hepatoma compared to liver. [2,3‐ 13 C 2 ]glucose and 13 C NMR simplify assessment of the PPP.
