Gluconeogenesis from Lactate in Rat Hepatocytes
1. In freshly prepared isolated rat liver cells there is a lag in gluconeogenesis from lactate. The magnitude of the lag increases with increasing lactate concentration. 2. The lag is virtually abolished by lysine. 3. A few other amino acids (tyrosine, arginine, asparagine, ornithine) and NH4Cl had effects similar to, but less pronounced than, lysine during the early stage of incubation. Lysine...
متن کاملQuantifying gluconeogenesis during fasting.
The use of2H2O in estimating gluconeogenesis' contribution to glucose production (%GNG) was examined during progressive fasting in three groups of healthy subjects. One group ( n = 3) ingested2H2O to a body water enrichment of ≈0.35% 5 h into the fast. %GNG was determined at 2-h intervals from the ratio of the enrichments of the hydrogens at C-5 and C-2 of blood glucose, assayed in hexamethylen...
متن کاملGluconeogenesis and fasting in cerebral malaria.
BACKGROUND In healthy subjects after an overnight fast, glucose production is for approximately 50% derived from glycogenolysis. If the fast is prolonged, glucose production decreases due to a decline in glycogenolysis, while gluconeogenesis remains stable. In cerebral malaria, glucose production is completely derived from gluconeogenesis after an overnight fast. It is not known if glucose prod...
متن کاملEstimation of gluconeogenesis in newborn infants.
The rate of glucose turnover (R(a)) and gluconeogenesis (GNG) via pyruvate were quantified in seven full-term healthy babies between 24 and 48 h after birth and in twelve low-birth-weight infants on days 3 and 4 by use of [(13)C(6)]glucose and (2)H(2)O. The preterm babies were receiving parenteral alimentation of either glucose or glucose plus amino acid with or without lipids. The contribution...
متن کاملHepatic redox state and gluconeogenesis from lactate in vivo in the rat.
1. To examine the role of the hepatic redox state on the rate of gluconeogenesis the effects of sodium crotonate injection (6mmol/kg body wt.) on rat liver metabolite concentrations and gluconeogenesis from lactate were studied in vivo. 2. Crotonate caused a marked oxidation of cytoplasmic and mitochondrial redox couples; decreases were observed in the ratios of [lactate]/[pyruvate], [glycerol ...
