Values are means ± SE. ¹³C NMR analysis of MAG derived from liver glycogen (n = 6), blood glucose (n = 6), and skeletal muscle glycogen (n = 6) of whole animals treated with [U-¹³C₃]lactate. Each value is the ratio of peak area of each resonance normalized by areas of methyl resonances of MAG on ¹³C NMR spectra (A_{each resonance}/A_methyl). Nos. in parentheses are excess ¹³C enrichment (%). Significantly different from blood glucose
