Under what physiological and hormonal conditions would you expect deamination to be carried out?

Deamination is the removal of an amine group from a molecule.

In the human body, deamination takes place in the liver. It is the process by which amino acids are broken down. The amino group is removed from the amino acid and converted to ammonia. The rest of the amino acid is made up of mostly carbon and hydrogen and is recycled or burned for energy. Ammonia is toxic to the human system, and enzymes convert it to urea or uric acid by addition of carbon dioxide molecules. Urea and uric acid can safely diffuse into the blood and then be excreted in urine.

I guess that amino-acids are broken down when carbohydrate and fat stores are exhausted,right?during starvation...
