Abstract
The activities of glutaminase and glutamate dehydrogenase in the small intestinal mucosa of infant rats were found to increase at the time of weaning. Pyruvate carboxylase activity, on the other hand, was very high during the suckling period and decreased to negligible values at weaning. It is suggested that gluconeogenesis in the infant mucosa occurs primarily via oxaloacetate and not via α-ketoglutarate.Keywords
