Turnover of liver glycogen in the rat foetus.
Incorporation and release of the radioactivity in the liver glycogen of 18.5- and 19.5-day-old rat foetuses were studied after intravenous injection of E11-14C]glycerol. Incorporation occurred during 1 h after injection of the radioactive tracer to the foetus; then, the incorporated radioactivity decreased. Glycogen content in the liver, and glycogen phosphorylase and glycogen synthase were not modified during the experiment. It is therefore postulated that a physiological turnover of glycogen exists in the liver of the rat foetus.
