Asparagine and glutamine are the products of amidations of aspartate and glutamate, respectively. Thus, asparagine and glutamine, and the two nonessential amino acids that are not directly the result of transamination of a-ketoacids because these are not common intermediates of the other pathways

Transamination reactions are readily reversible and can be used in the synthesis or the degradation of amino acids. Most amino acids participate in transamination reactions. Lysine is an exception;is is not transaminated.
