Load 3D Structure of Asparagine

L-Asparagine plays an important role in the biosynthesis of glycoproteins and is also essential to the synthesis of a large number of other proteins. The nervous system needs L-asparagine to maintain the equilibrium. This amino acid increases the resistance to fatigue, thereby stepping up the stamina of athletes. It enhances the smooth functioning of the liver.
