Abstract:
The integrated 13C NMR intensity of the glycogen C1 resonance was measured in skeletal muscle (biceps femoris region) of nine rabbits under in vivo conditions. Concurrent chemical determinations of glycogen content showed that the in vivo signal was 1.02 +/- 0.06 the intensity of analytical samples, where glycogen is known to be approximately 100% visible.
