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 else can I help you with?
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 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.
Where does the urea cycle take place in the body?
The urea cycle takes place in the liver.
What you should eat in high urea level in blood?
what should we eat when our urea lavel is high
Where is urea removed in the body?
Kidneys
Describe how the body removes urea?
The body removes urea through the kidneys via urine. Urea is a waste product produced in the liver during protein metabolism. It is filtered out of the blood by the kidneys and eliminated from the body through urination.
Is urea in milk?
Urea is a main component of urine so no it should not be.
What pass does urea take through the body?
Urea is produced in the liver as a waste product of protein metabolism. It is then filtered by the kidneys, where it is excreted in urine. Urea helps regulate the body's nitrogen balance and helps to remove toxic ammonia from the body.
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 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
How do you remove excess urea in the body?
Excess urea in the body is primarily removed by the kidneys through urine excretion. Increasing fluid intake can help dilute urea levels and promote its excretion. In severe cases, dialysis may be necessary to remove excess urea from the blood.
What is the liquid that carries urea out of the body?
The liquid that carries urea out of the body is urine. Urine is produced by the kidneys, which filter waste products, including urea, from the blood. It is composed primarily of water, electrolytes, and metabolic waste, and is excreted from the body through the urinary system.
