The liver is the primary site for the synthesis of nonessential amino acids and the degradation of excess amino acids. The kidneys are responsible for the excretion of the end products of amino acid metabolism, but not for their synthesis or degradation. The small intestine is responsible for the absorption of amino acids from the diet, but not for their synthesis or degradation. Skeletal muscle has an important role in protein synthesis, but it is not the primary site for the synthesis of nonessential amino acids or the degradation of excess amino acids. The large intestine is primarily responsible for the absorption of water and electrolytes, and not for the synthesis or degradation of amino acids.
