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.
The molecular formula of the urea is NH2-CO-NH2. The proteins are long chain of many amino acids. Urea is formed out of metabolism ( break down) of the amino acids.
Urea is synthesised in the liver, from the oxidation of amino acids and/or ammonia. Look up "urea cycle" for details about this process. It is then transported (in the blood) to the kidneys and excreted to the bladder, and exits the body with the urine.
