A: graph of peak area ratios, A_C2Q/A_C2D12 and A_C5Q/A_C5D56, based on ¹³C NMR analysis of MAG derived from liver glycogen, blood glucose, and skeletal muscle glycogen of whole animals treated with [U-¹³C₃]lactate (spectra shown in Fig. 6). B: graphs showing the relative distributions of multiply labeled glucose units in skeletal muscle glycogen originated from blood glucose (∼30%) and from de novo glycogen synthesis (∼70%) of the whole animals (spectra shown in Fig. 6C). **P < 0.01 and ***P < 0.001.
