Deamination is the process that removes an Amine group from a molecule.

Deamination of Nucleotide Bases:

Involves removing NH₂ (amino group) from an amino acid and forming ammonia (NH₃) by reacting the amino acid with oxygen ^[2].

The organic acid containing an oxygen with a double bond is usually respired.

Ammonia is a toxic substance to the body and is converted quickly into urea which is less harmful. The kidneys remove urea from the body.
