Figure 3. Incorporation of 14C-glucose into soleus muscle glycogen of offspring of Sprague-Dawley females fed diets differing in protein content during gestation and lactation. Rates of 14C glucose uptake into glycogen were determined in rat soleus muscle isolated from the offspring of mothers fed diets sufficient (20% whey protein; control: filled circle) or insufficient (5% whey protein; low-protein: open circle) in protein. Data represent the mean value±SD for 13 animals from three litters for control group, and 20 animals from four litters for low-protein group. There was no significant difference between the two groups at any insulin concentration.
