Pharmacology

Asparagine is a non-essential amino acid in humans, Asparagine is a beta-amido derivative of aspartic acid and plays an important role in the biosynthesis of glycoproteins and other proteins. A metabolic precursor to aspartate, Asparagine is a nontoxic carrier of residual ammonia to be eliminated from the body. Asparagine acts as diuretic. (NCI04)

How it is made

Produced by direct fermentation of carbohydrates

Isolated as a byproduct from the production of potato starch. A simple synthesis of L-asparagine from L-aspartic acid which is esterified to the beta methylester followed by treatment with ammonia.
