The effects of starvation and re-feeding on glycogen metabolism in mouse tail skin.

Although the glycogen content of mouse tail skin was decreased during starvation and was restored on re feeding, the proportion of glycogen synthase in the I form remained constant throughout at about 10% of the total. During the phase of net glycogen synthesis 1.5h after access to food was restored, the concentration of UDP glucose was markedly increased and the proportion of phosphorylase in the a form was significantly decreased.
