Urea or carbamide is an organic compound with the chemical formula (NH2)2CO. The molecule has two amine (-NH2) groups joined by a carbonyl (C=O) functional group.
Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals. It is solid, colourless, and odorless (although the ammonia which it gives off in the presence of water, including water vapor in the air, has a strong odor). It is highly soluble in water and non-toxic. Dissolved in water it is neither acidic nor alkaline. The body uses it in many processes, most notably nitrogen excretion. Urea is widely used in fertilizers as a convenient source of nitrogen. Urea is also an important raw material for the chemical industry. The synthesis of this organic compound by Friedrich Wöhler in 1828 from an inorganic precursor was an important milestone in the development of organic chemistry, as it showed for the first time that a molecule found in living organisms could be synthesized in the lab without biological starting materials.
The terms urea and carbamide are also used for a class of chemical compounds sharing the same functional group RR'N-CO-NRR', namely a carbonyl group attached to two organic amine residues. Example include carbamide peroxide, allantoin, and hydantoin. Ureas are closely related to biurets and related in structure to amides, carbamates, diimides, carbodiimides, and thiocarbamides.

What is the urea level in blood?
Urea is formed in the liver from excess proteins. Therefore, the blood that travels from the liver to the kidney via the heart has relatively high levels (but not unsafe levels) of urea. It is filtered completely in the kidneys, and passes out in the urine. Consequently, blood in the renal veins (ie. leaving the kidneys) should have no urea, as it is a toxin which, if allowed to accumulate in the body, can poison us.
Why is it important that the concentration of urea is kept very low in the dialysis fluid?
the concentration of urea should be kept low in the dialysis fluid because urea is harmful for our body if it is not removed.
What happens when your body makes to much ammonia?
They should be excreted. They are converted to urea and excreated
How do you remove excess urea in the body?
Urea is soluble in ethanol.
Where does urea cycle takes place?
ammonium ion, which is the end product of amino acid degradation, is toxic if allowed to accumulate. the urea cycle is a pathway that detoxifies the ammonium ions by converting it to urea - which is then transported to the kidneys to form urine... the function is to remove nitrogen waste from the body and avoid toxicity
What is urea made of?
Urea is made in the body by the liver, it is a by product produced in the process of removing ammonia, Ammonia is extremely toxic for the human body. Urea is then excreted from the blood filtered through the kidneys.
Where is urea removed from the body?
By filtration through the kidney.
Where is urea removed in the body?
Kidneys
What you should eat in high urea level in blood?
what should we eat when our urea lavel is high
Which toxic metal can accumulate in our body and cause chronic disease?
Lead is the metal which can accumulate in our body and cause chronic disease
Is urea in milk?
Urea is a main component of urine so no it should not be.
What is urea used for?
urea is used to produce NH3 and enter in many reactions as preparation of phthalimide urea is excreted from the body because it is a waste product and our bodies do not need it
