Urea, also called carbamide (because it is a diamide of carbonic acid), is an organic compound with chemical formula CO (NH2)2. This amide has two amino groups (– NH2) joined by a carbonyl functional group (–C (=O)–). It is thus the simplest amide of carbamic acid. [6]

2021年1月11日 · Urea, also known as carbamide, is a safe, useful compound with a significant history. It is a naturally occurring molecule that is produced by protein metabolism and found abundantly in mammalian urine.

urea, the diamide of carbonic acid, is most important degradation of protein catabolism in man, in other mammals & in certain other animal species. urea is formed in liver & forms the major part of organics in urine.

2024年6月2日 · Urea is a relatively non-toxic organic compound that aids in the breakdown of nitrogen-containing compounds and potentially toxic metabolic byproducts. Urea is produced in the liver through the Urea Cycle, which occurs in both …

2025年2月12日 · Urea, also known as carbamide, is an organic compound with chemical formula CO (NH2)2. This amide has two –NH2 groups joined by a carbonyl (C=O) functional group. Pure urea was first isolated from urine in 1727 by the Dutch scientist Herman Boerhaave, and he extracted urea from urine by working with the concentated-by-boiling residue.

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.

2024年4月22日 · Urea is a solid of molecular formula H 2 NCONH 2 with a molar mass (60.024 g/mol). It has a density under normal conditions of 0.74 g/cm 3. It has a melting point (mp = 132.7 ºC). It is very soluble in water (108 g of urea dissolve in 100 ml of H 2 O at a temperature of 20 ºC), it is also very soluble in alcohol but insoluble in chloroform ...
