Urea, also called carbamide (because it is a diamide of carbonic acid), is an organic compound with chemical formula CO(NH 2) 2.This amide has two amino groups (– NH 2) joined by a carbonyl functional group (–C(=O)–). It is thus the simplest amide of carbamic acid. [6]Urea serves an important role in the cellular metabolism of nitrogen-containing compounds by animals and is the main ...

尿素（Urea）是由碳、氮、氧和氫組成的有機化合物，又稱脲（與尿同音）。 其化學式為 CON 2 H 4 、 (NH 2) 2 CO 或 CN 2 H 4 O ，分子質量60，國際非專利藥品名稱為 Carbamide （碳醯胺）。 外觀是無色晶體或粉末，是動物蛋白質代謝後的產物，通常用作植物的氮肥。 尿素在肝合成，是哺乳動物排出的體內含 ...

尿素（Urea），又称脲、碳酰胺，化学式是CH4N2O或CO(NH2)2，是一种白色晶体，无味无臭，易溶于水、乙醇和苯，微溶于乙醚、氯仿。尿素是最简单的有机化合物之一，是哺乳动物和某些鱼类体内蛋白质代谢分解的主要含氮终产物，可以用作化肥、动物饲料、炸药、胶水稳定剂和化工 …

2025年2月20日 · Urea, the diamide of carbonic acid. It has important uses as a fertilizer and feed supplement, as well as a starting material for the manufacture of plastics and drugs. It is a colorless, crystalline substance that melts at 132.7 degrees C (271 degrees F) …

2024年6月2日 · Urea is the final, non-toxic product of such a metabolic cycle, which can then be eliminated from the body. Before we go into the details of why urea is so important, let’s take a look at how and where it is produced. Urea chemical formula (Photo Credit : Anastasiya Litvinenka/Shutterstock)

2025年2月12日 · Urea is a white crystalline so lid. Chemical Properties. Urea,CO(HN2)2, also known as carbamide, is a white crystalline powder that has a melting point of l32.7 °C (270 °F). It is a natural product of animal protein metabolism and is the chief nitrogen constituent of urine. Commercially, urea is produced by the reaction of ammonia and carbon ...

Urea is an organic compound.It was first found in urine in 1773 by the French chemist Jean Rouelle.It is also called Carbamide, and its chemical names are Carbonyl Diamide (used in inorganic chemistry) and Diaminomethanal (used in organic chemistry).. In humans, it is a normal component of blood and many body tissues. It is produced in the liver, where ammonia, a very toxic substance, is ...

2021年1月11日 · Typically, ammonia and urea are manufactured in the same plant so that some of the carbon dioxide byproduct from ammonia production can be used to make urea. Global urea production capacity is ≈220 million t/year. Why is urea produced in such large quantities? The answer is that, other than ammonia, urea has the highest nitrogen content of ...

Urea is a multifaceted compound with significant roles in human physiology, agriculture, and industry. Understanding its functions and applications is essential for leveraging its benefits while minimizing potential environmental impacts. As research continues, the importance of urea in various fields will likely expand, highlighting its ...

However, the association constant in benzene is 40 M-1, so urea exists only as the dimer in benzene. Why is the urea dimer a thousand times more stable in benzene than in water? The answer is that water forms hydrogen bonds to urea and at a concentration of 55 M, water molecules fill the urea hydrogen bonding sites most of the time. Acetic acid ...
