The effect of dietary composition and of insulin on gluconeogenesis in rainbow trout (Salmo gairdneri).
1. The activities at 15" of three gluconeogenic enzymes, D-fructose-l,6-diphosphate, 1-phosphohydrolase (EC 3.1.3.1 l), pyruvate carboxylase (EC 6.4.1.1) and phosphoenolpyruvate carboxykinase (4.1.1.32), were determined in liver, kidney, gill and muscle of rainbow trout (Sulmo guirdneri) given a commercial diet. The results indicated that liver and kidney are the main sites of gluconeogenesis. ...
متن کاملThe regulation of gluconeogenesis by diet and insulin in rainbow trout (Salmo gairdneri).
1. The effects of diet composition and insulin treatment on blood glucose level, blood amino acid concentrations, the activities of two hepatic gluconeogenic enzymes (fructose diphosphatase, EC 3.1 .3.11; phosphoenolpyruvate carboxykinase, EC 4 .1 . 1 .32) and of two hepatic glycolytic enzymes (hexokinase, EC 2 .7 .1 . 1 ; pyruvate kinase, EC 2 . 7 . 1 .40) were examined in rainbow trout (Sulmo...
متن کاملThe effect of dietary lysine levels on growth and metabolism of rainbow trout (Salmo gairdneri).
Groups of rainbow trout (Salmo gairdneri; mean weight 5 g) were given diets containing 10, 12, 14, 17, 21, 24 and 26 g lysine/kg diet for 12 weeks. By analysis of the growth values the dietary requirement of lysine in this experiment was found to be 19 g/kg diet. A similar requirement value was obtained from a dose-response curve of expired 14CO2 (following an intraperitoneal injection of L-[U-...
متن کاملThe effect of low dietary manganese intake on rainbow trout (Salmo gairdneri).
1. Rainbow trout (Salmo gairdneri) of mean initial weight 15 g were given either a low-manganese or control diet containing 1.3 and 33 mg Mn/kg dry diet respectively. 2. Weight gains over a 24-week feeding period were the same for both groups of trout. 3. Hepatosomatic index, blood packed cell volume and haemoglobin concentration, plasma protein and the activities of aspartic aminotransferase (...
متن کاملLactate and Proton Dynamics in the Rainbow Trout (salmo Gairdneri)
Chronically cannulated rainbow trout were subjected to 6 min of severe burst exercise and monitored over a 12 h recovery period. There were shortlived increases in haematocrit, haemoglobin, plasma protein, Na and Cl~ levels. Plasma [Cl~] later declined below normal as organic anions accumulated. A much larger and more prolonged elevation in plasma [K] probably resulted from intracellular acidos...
