Gluconeogenesis, the formation of glucose from non-glucose carbon precursors, is expressed for the first time in most mammalian species immediately after birth. The appearance of gluconeogenesis, along with the contribution of glycogenolysis, is responsible for the maintenance of a steady rate of glucose production. The recent development of novel tracer isotopic methods have allowed precise quantification of the contribution of gluconeogenesis to glucose production in newborn infants and adults. These data show that gluconeogenesis is active both during fasting and during the fed state. In the healthy human newborn following a brief fast, gluconeogenesis via pyruvate contributes -30% to total glucose production.
