Deamination is the process through which excess amino acids are broken down into ammonia and a keto acid. Amino acids are the building blocks of proteins, and when we consume more protein than our body needs, the excess amino acids must be eliminated. The process of deamination takes place in the liver and kidneys, where enzymes remove the amino group from the amino acid and convert it into ammonia. The ammonia is then converted into urea and eliminated from the body in urine. The remaining keto acid can be used for energy or converted into glucose or fat for storage.
