The molecule has two —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 colorless, odorless solid, highly soluble in water, and practically non-toxic (LD50 is 15 g/kg for rats).  Dissolved in water, it is neither acidic nor alkaline." ] ,
