The amide group(-CONH) of asparagine can be easily hydrolyzed to amino group(-NH4) and carboxyl group(-COON) and form aspartic acid. This conversion is related to the molecular basis of aging. It located on the surface as well inside the proteins due to the ability of formation of hydrogen bond through amide group of molecule. Asparagine (http://www.guidechem.com/cas-70/70-47-3.html) also acts as a common site for the bonding of carbohydrates in glycoproteins.
Asparagine is used to produce aspartic acid and ammonia in some biochemical reactions catalyzed by enzyme such as asparaginease. Aspartic acid can be changed into oxalo acetic acid. Asparagine is involved in the preservation of central nervous system and vital for the correct functioning and health of the nerves.
