Gluconeogenesis in Birds
It is a characteristic of all avian species that they maintain a plasma glucose concentration between 9 and 15 mM under all physiological circumstances. Even starvation for up to 9 days failed to lower the blood sugar concentration of chickens (Hazelwood & Lorenz, 1959). This concentration is much greater than that found in most mammals and yet, by contrast, the glycogen stores of avian liver a...
متن کاملCerebral Gluconeogenesis and Diseases
The gluconeogenesis pathway, which has been known to normally present in the liver, kidney, intestine, or muscle, has four irreversible steps catalyzed by the enzymes: pyruvate carboxylase, phosphoenolpyruvate carboxykinase, fructose 1,6-bisphosphatase, and glucose 6-phosphatase. Studies have also demonstrated evidence that gluconeogenesis exists in brain astrocytes but no convincing data have ...
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 کاملInborn Error of Gluconeogenesis
In 1951 Leigh described a condition which is now known as subacute necrotizing encephalomyelopathy. Ebels, Blokzijl, and Troelstra (1965) have summarized findings in 28 of these patients, all of whom died. Since then 6 further cases have been described by Worsley et al. (1965), Namiki (1965), Lakke, Ebels, and ten Thye (1967), and Clayton, Dobbs, and Patrick (1967). The metabolic background of ...
متن کاملGeneration of extramitochondrial reducing power in gluconeogenesis.
1. Kidney-cortex slices incubated with pyruvate formed glucose and lactate in relatively large and approximately equimolar quantities. The formation of these products involves two exclusively cytoplasmic NADH(2)-requiring reductions, catalysed by lactate dehydrogenase and triose phosphate dehydrogenase. From the rates of glucose and lactate formation it can be calculated that over 1000mu-moles ...
