deamination

Removal of the amino group from a molecule. When an NH2 group is replaced by an oxygen atom a ketone is formed and the process is described as oxidative deamination. If the amino group is terminal, the process should, strictly, be called deamidation.

deamination

the removal of the amino group (NH2) from a molecule, as in the release of ammonia (NH3) from AMINO ACIDS, the residue of which can then enter the KREBS CYCLE usually via ACETYLCOENZYME A. The amino group then enters the ORNITHINE CYCLE.
