An In Vivo Nuclear Magnetic Resonance Spectroscopic Study

Using 3C nuclear magnetic resonance spectroscopic methods we examined in vivo the synthesis of liver glycogen during the infusion of D-11-13Cjglucose and the turnover of labeled glycogen during subsequent infusion of D-11-13Cjglucose. In fasted rats the processes of glycogen synthesis and degradation were observed to occur simultaneously with the rate of synthesis > degradation leading to net glyc…
