Molecular and enzymatic analysis of ammonium assimilation in woody plants.
Ammonium is assimilated into amino acids through the sequential action of glutamine synthetase (GS) and glutamate synthase (GOGAT) enzymes. This metabolic pathway is driven by energy, reducing power and requires the net supply of 2-oxoglutarate that can be provided by the reaction catalysed by isocitrate dehydrogenase (IDH). Most studies on the biochemistry and molecular biology of N-assimilati...
متن کاملSteady state analysis of nitrate-ammonium assimilation by phytoplankter? 2
The ammonium:nitrate delivery ratio to cells of Dunaliella tertiolecta in continuous culture had no effect on the ambient nitrate concentrations at steady state, indicating that the assimilation of these radicals is competitive, not suppressive, under nitrogen limiting conditions. The physiological parameters, C : cell and Chl: cell, were invariant over the range of delivery ratios. Cellular gr...
متن کاملThe differential toxicity of ammonium salts.
The relationship between liver disease and ammonia toxicity has been known since the discovery of meat intoxication in Eck fistula dogs (1-4). The similarity between this syndrome and clinical hepatic coma stimulated the study of ammonia toxicity in humans. This proceeded from oral administration (5-10) to intravenous infusion (11, 12) and finally to the development of an "ammonia tolerance tes...
متن کاملMicrowave synthesis of quaternary ammonium salts.
The microwave synthesis of several quaternary ammonium salts is described. The synthesis provides comparable or better yields than published methods with reduced reaction times and in the absence of solvent.
