They are not stored, but excreted as nitrogenous waste

Detailed explanation-1: -Amino acids are transported to the liver during digestion and most of the body’s protein is synthesised here. If protein is in excess, amino acids can be converted into fat and stored in fat depots, or if required, made into glucose for energy by gluconeogenesis which has already been mentioned.
Detailed explanation-2: -The urea is the primary nitrogenous waste formed by the breakdown of amino acids in the body. Mammals are the main producers of urea as they secrete urea as the major nitrogenous waste product in the body.
Detailed explanation-3: -The less toxic nitrogenous compound urea is produced together with water. This series of reactions is called the ornithine cycle. The urea and water are released from the liver cells to the bloodstream and transported to the kidneys where the blood is filtered and the urea is passed out of the body in the urine.
Detailed explanation-4: -When you eat proteins, the body breaks them down into amino acids. Ammonia is produced from leftover amino acids, and it must be removed from the body. The liver produces several chemicals (enzymes) that change ammonia into a form called urea, which the body can remove in the urine.
