The urea cycle (also known as the ornithine cycle) is a cycle of biochemical reactions that produces urea (NH2)2CO from ammonia (NH3). Animals that use this cycle, mainly amphibians and mammals, are called ureotelic. The urea cycle converts highly toxic ammonia to urea for excretion. This cycle was the first metabolic cycle to be discovered (Hans Krebs and Kurt Henseleit, 1932), five years before the di… Web5 okt. 2005 · In lactic acidosis, ketoacidosis and in acidosis when the anion gap was elevated by unclear mechanisms, they found significant increases in intermediates of the citric acid (Krebs) cycle. This did not occur in normal anion gap acidosis. The raised anion gap groups displayed increases across the board in isocitrate, α-ketoglutarate and malate.
