title: Factors affecting gluconeogenesis in the neonatal subhuman primate (Macaca mulatta).
abstract: The capacity for gluconeogenesis has been studied in 33 subhuman primate newborn (Macaca mulatta) in the basal steady state. Basal blood glucose levels were seen to rise with increasing postnatal age. Availability of the major gluconeogenic substrates, alanine and lactate, was adequate at times when blood glucose and the rate of gluconeogenesis were low. Hepatic and renal cortical content of the four key gluconeogenic enzymes was low during the 1st week of life compared to adult levels. Diminished induction of the gluconeogenic enzymes did not appear to be the cause of low blood glucose levels. The serum-free fatty levels were directly correlated to both the basal glucose levels and to the rate of gluconeogenesis.
