The formation of urea in the liver helps eliminate toxic ammonia from the body. Ammonia is a byproduct of protein metabolism and can be harmful if it accumulates in high levels. By converting ammonia to urea, the body can safely excrete it through urine, preventing poisoning.

Can mineral water help prevent the formation of kidney stones?
Yes, mineral water can help prevent the formation of kidney stones by keeping the body hydrated and flushing out toxins that can contribute to stone formation. The minerals in the water can also help regulate the body's pH levels, which can reduce the risk of developing kidney stones.
What is the substrate for urease?
The substrate for urease is urea. Urease catalyzes the hydrolysis of urea into ammonia and carbon dioxide.
Excess nitrogen is converted in what by the liver?
Excess nitrogen is converted into urea by the liver through a process called the urea cycle. Urea is then excreted in urine by the kidneys to maintain nitrogen balance in the body.
What is an anticoagulant substance produced by basophils and tissue cells to prevent formation of thrombi and emboli?
Heparin is an anticoagulant substance produced by basophils and tissue cells. It helps prevent the formation of blood clots (thrombi) and dislodged blood clots (emboli) in the bloodstream.
What enzyme is responsible for metabolizing urea?
The enzyme responsible for metabolizing urea is urease. Urease breaks down urea into ammonia and carbon dioxide.
Which biomolecule breakdown causes the formation of urea?
The breakdown of amino acids, specifically arginine and ornithine, in the liver results in the formation of urea. This process is known as the urea cycle or ornithine cycle, and it plays a key role in removing toxic ammonia from the body.
When precipitating calcium oxalate what is the purpose of adding urea?
Urea is added when precipitating calcium oxalate to increase the solubility of the calcium oxalate crystals. This helps to prevent the formation of large, dense crystals that can be difficult to filter and wash. By adding urea, smaller and more easily filterable crystals are formed.
Why the color of urea is yellow?
Urea can turn yellow due to the degradation of urea into ammonia and biuret under certain conditions, such as exposure to high temperatures or alkaline environments. This process can result in the formation of colored compounds, which can give the urea a yellow hue.
What is the significance of urea cycle in the formation of amino acids?
Over all reaction of Urea Cycle. NH4 + CO2 + Aspartate + 3 ATP ---> Urea + Fumarate + 2 ADP + 2 Pi + AMP + PPi Formula is formed.

How does pH effect the stability of aqueous urea?
The stability of aqueous urea is affected by pH because urea can undergo hydrolysis in alkaline conditions, leading to the formation of ammonia and carbon dioxide. In acidic conditions, urea is more stable due to lower hydrolysis rates. Therefore, maintaining a neutral pH is important for the stability of aqueous urea solutions.
What percent of urea is filtered and recycled?
Approximately 50-60% of urea is filtered and recycled through the kidneys during the process of urine formation. The rest is excreted out of the body in urine.

What are nitrogenous wastes created from urine formation?
Nitrogenous wastes created during urine formation include urea, creatinine, and uric acid. These substances are byproducts of protein metabolism and the breakdown of nucleic acids. They are filtered by the kidneys and excreted in urine to maintain proper balance in the body.
Chemical equation of urea in chemistry?
The chemical equation for the formation of urea is: (NH₂)₂CO(s) --> CO(NH₂)₂(l) Urea is formed by the condensation reaction of ammonia and carbon dioxide.
What is the principle of Sodium hypobromite test for urea?
The principle of the Sodium hypobromite test for urea is based on the reaction between urea and sodium hypobromite, which results in the formation of nitrogen gas. Urea is hydrolyzed to form ammonia and carbon dioxide, which react with sodium hypobromite to liberate nitrogen gas that can be detected by its characteristic effervescence. This test is used to detect the presence of urea in a sample.
