explain transamination

Transamination − Transfer of the amino group from one amino acid to the keto group of the ketoacid, catalyzed by the enzyme transaminase.This enzyme is found within both the cytoplasm and mitochondria.

E.g., formation of amides, asparagine and glutamine from amino acids, aspartic acid and glutamic acid, by the addition of another amino group to each.


Transamination reaction participate in the synthesis of most amino acids. Glutamatic acid is the source of amino group (NH2) for most other amino acids through transamination reaction.
