Answer:
Urea
Explanation:
Urea is a substance produced naturally in our body and is considered a non-protein nitrogenous compound. It is produced by the liver and is eliminated by the urine because it cannot be contained in the body for a long time. It is formed when amino acids are broken down, when they are in excess in the blood.
Urea is basically composed of nitrogen, oxygen, carbon and hydrogen. In addition, it makes up 2 to 5% of urine.
