What is a transamination reaction? What is its significance?

Explanation

Transamination :
In this process, the amino group is transferred from one amino acid to the keto group of a keto-acid.
Glutamic acid is the main amino acid which transfers its `NH_(2)` group to form seventeen other amino acid.
The reaction is catalysed by the enzyme transaminase.
`R underset("Amino-Donor")underset(NH_3^+)underset(|)overset(H)overset(|)(C)-COO+r_(2)-underset("Amino-Acceptor")underset(O)underset(||)(C)-COO`
`R-underset(O)underset(||)(C)-COO+R_(2)-underset(NH_3^+)underset(|)overset(H)overset(|)(C)-COO`
It results in formation of amino acids.
