What is the principal product of the urea cycle in the liver for ammonia detoxification?

Explanation:
The urea cycle in the liver converts toxic ammonia into a non-toxic, water-soluble waste that can be safely excreted. During this process, ammonia combines with carbon dioxide through a series of steps to form urea, which is then released into the bloodstream and eliminated by the kidneys. Urea is the principal product because it effectively disposes of excess nitrogen from amino acid breakdown, is far less toxic than ammonia, and is readily excreted in urine. In contrast, uric acid comes from purine metabolism and creatinine from muscle metabolism, so they are not the main products of this detoxification pathway.
