WebUrea is the major nitrogenous waste product, making up some 80% of it. Urea is formed in the liver, and is excreted by the kidneys in the urine along with the other types of protein waste products. The destruction of proteins in the body gives rise to two classes of waste products: nitrogenous and non-nitrogenous. The non-nitrogenous types of waste … WebDeamination of amino acids results in the production of ammonia (NH 3).
