Urea cycle: What is the urea cycle

What is the urea cycle . Where does it occur. What is the function of the pathway. Learn the pathway with steps, regulations, and a diagram. The urea cycle (also known as the ornithine cycle) is a cycle of biochemical reactions that produces urea (NH 2) 2 CO from ammonia (NH 3 ). Animals that use this cycle, mainly amphibians and mammals, are called ureotelic. The urea cycle is the body’s way of converting toxic ammonia into urea. Ammonia originates from protein catabolism whether that is secondary to a high-protein diet, deaminations, or during the period of prolonged starvation. The urea cycle , also known as the ornithine cycle, is a vital metabolic pathway responsible for the conversion of ammonia into urea. This cycle plays a pivotal role in the body’s mechanism to eliminate excess nitrogen.
