Urea is a colorless, odorless compound that is primarily found in urine. It is produced in the liver as a waste product from the breakdown of proteins. Urea plays a crucial role in the body's nitrogen balance, helping to eliminate excess nitrogen from the body. In addition to its biological significance, urea is widely used in agriculture as a nitrogen-rich fertilizer. It is also utilized in various industrial applications, including the production of plastics and resins. Urea's chemical formula is CO(NH₂)₂, indicating it contains carbon, oxygen, and nitrogen atoms.
