Itâs not a major part of any starvation response. Once proteins are degraded, the amino acids may be used in anabolism to make new proteins, or may be catabolized to produce energy. Amino acid catabolism produces ammonia (NH3) and the carbon skeleton. Ammonia is toxic and has to be managed by the urea cycle.
The fate of an amino acid after it is transported to the liver is highly dependent on the body's needs for that moment. Some amino acids enter the blood stream, where they join amino acids that have been liberated during the constant breakdown and synthesis of body tissue. Other amino acids are used by the liver to manufacture many of the specialized proteins such as liver enzymes, lipoproteins, and the blood protein (albumin).
