Trivia questions : What is urea?

Nitrite definition

Urea, also known as carbamide, is an organic compound composed of carbon, nitrogen, oxygen, and hydrogen. It is a white crystal. One of the simplest organic compounds is the main nitrogen-containing end product of protein metabolism in mammals and certain fish. It is also the nitrogen fertilizer with the highest nitrogen content.

Urea chemical formula and Urea molar mass

Chemical formula: CO (NH2) 2
Molecular formula: CH4N2O
Molar mass: 60.056 g · mol -1
Exact mass: 60.03240

Urea structure

CO (NH2) 2 urea is commonly known as carboxamide, also known as urea, is a full amide of carbonic acid, the structural formula is H2N-CO-NH2.

Urea synthesis

Method one
Carbon dioxide and ammonia are used to synthesize ammonium carbamate under high temperature and high pressure. After decomposition, absorption and conversion, they are crystallized, separated and dried.

Method Two
The preparation method is to mix purified ammonia and carbon dioxide at a molar ratio of 2.8 to 4.5 into the synthesis tower. The pressure in the tower is 13.8 to 24.6 MPa, the temperature is 180 to 200 ° C, and the residence time of the reaction material is 25 to 40 minutes. The urea solution of ammonia and ammonium carbamate is decompressed and cooled to evaporate the urea solution separated from ammonia and ammonium carbamate to more than 99.5%, and then granulated in a granulating tower to obtain a urea product.

Method three
The end product of protein metabolism in mammals in urea. In 1922, the industrialized production of urea from ammonia and carbon dioxide was realized in Germany. Ammonia reacts with carbon dioxide to form urethane, which is then dehydrated to form urea.

Industrial law
Production method: industrially use liquid ammonia and carbon dioxide as raw materials to directly synthesize urea under high temperature and high pressure conditions

Urea nitrogen

Refers to "blood urea nitrogen", a nitrogen-containing compound in the plasma other than protein, which is filtered from the glomerulus and excreted. When renal insufficiency is decompensated, BUN will increase. Therefore, it is clinically used as an index for judging glomerular filtration function.

Urea nitrogen low

1. Renal dysfunction. Low urea nitrogen may be related to eating too little protein, pregnancy, and liver failure.
2. Liver failure. The liver is an important metabolic organ of the human body, and liver failure causes normal absorption of nutrients. Another reason is insufficient protein intake of the patient, coupled with large consumption due to abnormal liver function.

Urea nitrogen high

1. Organic renal impairment: ⑴ Chronic renal failure caused by various primary glomerulonephritis, pyelonephritis, interstitial nephritis, kidney tumors, and polycystic kidney disease. ⑵ When renal function is slightly impaired in acute renal failure, BUN may not change, but GFR (glomerular filtration rate) drops below 50% for BUN to increase. Therefore, blood BUN measurement cannot be used as an indicator of early renal function. However, for chronic renal failure, especially the increase in BUN in uremia is generally consistent with the severity of the disease: the GFR of the renal failure compensatory phase has decreased to 50 ml / min, and the blood BUN <9 mmol / L; the renal failure decompensated phase, the blood BUN> 9mmol / L; blood BUN> 20mmol / L during renal failure.
2, prerenal oliguria: such as severe dehydration, a large amount of ascites, cardiac circulation failure, hepatorenal syndrome, etc. due to insufficient blood volume, decreased renal blood flow and insufficient perfusion leading to oliguria. At this time, BUN increased, but creatinine did not increase significantly. BUN / Cr (mg / dl)> 10: 1, which is called prerenal azotemia. Urine volume can increase after expansion. BUN can decrease by itself.
3. Excessive protein breakdown or ingestion, such as acute infectious diseases, high fever, upper gastrointestinal bleeding, large-scale burns, severe trauma, major surgery and hyperthyroidism, high protein diet, etc., but serum creatinine generally does not increase.

Urea cycle

Protein is broken down into amino acids in the body, and then broken down to produce ammonia. Excess ammonia is neurotoxic. The detoxification of ammonia is the synthesis of urea in the liver, which is then excreted with urine. The metabolic pathway of synthetic urea is called the urea cycle, thereby maintaining normal blood ammonia levels.

Urea cycle disorder

The urea cycle disorder refers to when a certain enzyme in the urea cycle has a congenital defect, the ammonia synthesis of urea fails, and free ammonia accumulates in the body to form hyperammonemia. Clinically manifested as severe brain dysfunction.

Urea uses

Urea fertilizer

Urea is a high-concentration nitrogen fertilizer. It is a neutral and quick-acting fertilizer and can also be used to produce a variety of compound fertilizers. No harmful substances remain in the soil, and no adverse effects are caused by long-term application. Animal husbandry can be used as feed for ruminants. Urea is an organic nitrogen fertilizer that can be absorbed and used by crops after being hydrolyzed into ammonium carbonate or ammonium bicarbonate by the action of urease in the soil. Therefore, urea should be applied 4-8 days before the fertile period of the crop. Urea is suitable for basal fertilizer and top dressing, and sometimes used as seed fertilizer. Urea is suitable for all crops and all soils. It can be used as a base fertilizer and topdressing. It can be applied in dry paddy fields. Urea can promote cell division and growth, making branches and leaves grow lush.

Urea cream

Urea cream is a kind of beauty skin care products. The main ingredients are urea (not agricultural urea) 8%, petroleum jelly 10%, chlorhexidine acetate 0.03% to 0.06% and so on. The method of use is morning and evening skin exfoliation.

Urea lotion

Urea lotion is a kind of over-the-counter medicine commonly used in dermatology. The main ingredient is urea. The medicine can dissolve and degrade keratin, and promote hydration of the stratum corneum, thereby softening the skin and preventing chapped skin. It can be applied 2-3 times a day after topical application, and massaged topically after application to promote drug absorption. Therefore, it has a wide range of uses, such as for simple cleft palate, cleft palate caused by keratosis of hand and foot, various types of ichthyosis, senile skin pruritus, sebum-deficient eczema, and emollient after bathing. However, side effects rarely occur, and individual symptoms such as burning sensation and itching can occur.

Urea for lawns

The amount of nitrogen fertilizer on the lawn should not be too large, otherwise it will cause the lawn length to increase the number of pruning and reduce the ability of the lawn to resist environmental stress. 30 to 50 kilograms per acre, the annual nitrogen application rate of turf with low maintenance level is about 4 kilograms per acre.

Urea side effects

1. Urea is stored for too long or the temperature of the medicinal solution is too low, which can cause flushing, mental excitement, irritability and other symptoms after injection.
2. Urea is highly irritating, and local injection may cause venous spasm pain, phlebitis, or venous thrombosis; leakage under the skin may cause local swelling, blistering, and even tissue necrosis. Occasionally mild local irritation.

Urea test

Urea breath test

The urea breath test includes two methods, carbon 13 and carbon 14, and is a common method for detecting Helicobacter pylori. This method is non-invasive for detecting H. pylori, simple and easy to perform, and has high sensitivity. Helicobacter pylori is a kind of bacteria colonized in the gastric mucosa and is infectious. It is an important factor in the development of active gastritis, gastric ulcers, and even gastric mucosa-associated lymphomas and gastric cancer. Many hospitals can now carry out this test, which is a common test item in the department of gastroenterology.


Mammals produce urea in a circulatory response in the liver. Animal husbandry can be used as a feed for ruminants, as is dairy cow husbandry. So there may be urea residues in the milking process that causes milk. The Urea Rapid Test For Milk Kit provided by BALLYA  can effectively detect whether the urea content in milk exceeds the standard. This kit is easy to operate and has a short detection time and high accuracy. The test results comply with EU standards.
