Urea

Urea plays a crucial role in animal metabolism and is excreted in urine. It is extensively used as a fertilizer in agriculture due to its nitrogen content. Chemically, urea consists of two amine groups connected by a carbonyl group. Although urea is a white, odorless solid, it releases ammonia when in contact with water, which has a strong smell.
