Urea is naturally produced in the liver of mammals as a result of the urea cycle, a process of nitrogen waste excretion. Industrially, urea is synthesized through the Bosch-Meiser process, which involves the reaction of ammonia and carbon dioxide under high temperature and pressure. Its ...
Terrestrial vertebrates produce it in the urea cycle, in which one nitrogen atom of urea is captured from a NH4? ion, while the other comes from aspartate. The carbon atom present in urea comes from CO2. Mammals produce urea in the liver, after which it is 123 J Appl Electrochem (2016)...

Here, using a high-protein diet rat model and a network-based strategy, it is found that high urinary urea concentration activated pathways including inflammatory response, cell cycle arrest, apoptosis and cancer in urothelium of rats with high-protein diet. These findings suggest a potential conn...
a. Diagram of how 15N-labeled ammonia incorporates into the urea cycle intermediates. b. Sirt4 knockout increases ammonia incorporation into urea cycle metabolites. The incorporation of 15 N into CP, citrulline, arginino-succinate, arginine and urea were determined in wild-type and Sirt4...
