Element 117, discovered by Laboratory, one step closer to being named. Element 117, first discovered by Lawrence Livermor escientists and international collaborators in 2010, is one step closer to being named.
Urea or carbamide is an organic compound with the chemical formula C O (N H 2) 2. The molecule has two âNH 2 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 colorless, odorless solid, highly soluble in water, and practically non-toxic (LD50 is 15 g/kg for rats).rea production occurs in the liver and is regulated by N-acetylglutamate. Urea is then dissolved into the blood (in the reference range of 2.5 to 6.7 mmol/liter) and further transported and excreted by the kidney as a component of urine.
