Hypoglycemia, Gluconeogenesis and the Brain
1991The purpose of this chapter is to review the role which gluconeo- genesis plays in the response to insulin-induced hypoglycemia and to assess the influence of the brain in driving that response. The chapter is divided into three parts: the response of gluconeogenesis to hypoglycemia; the role of the brain in driving hormone secretion, and as a result ...

Gluconeogenesis and nitrogen metabolism in maize
Plant Physiology and Biochemistry, 2018Two pathways can be used by gluconeogenesis in plants: one employs phosphoenolpyruvate carboxykinase (PEPCK) and the other pyruvate orthophosphate dikinase (PPDK). The occurrence-location of these enzymes was determined in developing kernels of maize. PPDK was much more abundant than PEPCK in extracts of whole kernels.

Gluconeogenesis is defined as the net formation of glucose from non-carbohydrate precursors such as pyruvate, lactate, glycerol, and certain amino acids. It is crucial for survival because glucose, the primary substrate for a number of tissues, most notably the brain, is only available during feeding, and liver glycogen stores can only provide glucose ...

Gluconeogenesis in the suckling rat.
American Journal of Physiology-Endocrinology and Metabolism, 1977Gluconeogenesis from lactate was increased more than twofold in perfused livers and isolated hepatocytes from 10- and 15-day-old suckling rats compared with adult rats and was not increased by fasting. Glucagon (10(-19)-10(-7) M) induced minimal activation of gluconeogenesis in hepatocytes from such animals even though it promoted accumulation of cAMP.

Regulation of Gluconeogenesis by Glucocorticoids
19791. Regulation of gluconeogenic substrate supply and modulation of the gluconeogenic pathway in the liver are both important in the control of gluconeogenesis by glucocorticoids. 2. Adrenal deficiency decreases the release of gluconeogenic and other amino acids from skeletal muscle during starvation. The effect is reversed by glucocorticoid replacement.

Hormonal Control of Gluconeogenesis
1979Gluconeogenesis is the process by which glucose and glycogen are synthesized in the animal body from noncarbohydrate precursors. The liver and the kidney are the two organs which carry out gluconeogenesis and gluconeogenic substrates include lactate, pyruvate, glycerol, and the glucogenic amino acids. Although all the natural amino acids except leucine

Gluconeogenesis and Glycogenolysis in Health and Diabetes
Journal of Investigative Medicine, 2004Reviewed are data on gluconeogenesis (GNG) and glycogenolysis (GL) obtained in healthy volunteers and diabetic patients with newer, quantitative methods. Specifically addressed are effects of overnight and prolonged fasting, of acute changes in serum insulin and plasma free fatty acid (FFA) levels, as well as acute changes of combined FFA and insulin ...
