Whenever one consumes proteins, after using the amino acids in the body for protein synthesis, the waste product that is produced is urea. Urea is soluble in water. It is how nitrogen is excreted by the body. The body is unable to store excess protein. Therefore, after digestion by the stomach and small intestine, the amino acids which are protein's endproducts enter the bloodstream. Excess amino acids are converted in the liver to other products by the process of deamination. The nitrogen in the amino acid becomes converted to ammonia, and this is further converted by the liver into urea, which is less toxic than ammonia to the body. The kidneys will then filter out the urea from the circulation, send it to the bladder along with water and excrete it in the form of urine.
