WebbNitrogenous Waste in Terrestrial Animals: The Urea Cycle. The urea cycle. is the primary mechanism by which mammals convert ammonia to urea. Urea is made in the liver and excreted in urine. The overall chemical reaction by which ammonia is converted to urea is 2 NH 3 (ammonia) + CO 2 + 3 ATP + H 2 O → H 2 N-CO-NH 2 (urea) + 2 ADP + 4 P i + AMP. WebbOne way to measure how well dialysis is removing urea from the body is to measure blood urea nitrogen (BUN) level. The BUN is measured before and after your treatment session. Then the two numbers are compared to see how much the urea level in the blood has gone down. This difference is called the urea reduction ratio (URR).
