Aspartic Acid

Description

What is Aspartic Acid?

Aspartic Acid is a non-essential amino acid in humans, Aspartic Acid has an overall negative charge and plays an important role in the synthesis of other amino acids and in the citric acid and urea cycles. Asparagine, arginine, lysine, methionine, isoleucine, and some nucleotides are synthesized from aspartic acid. Aspartic acid also serves as a neurotransmitter.

L-aspartic acid is the L-enantiomer of aspartic acid. It has a role as an Escherichia coli metabolite, a mouse metabolite and a neurotransmitter. It is an aspartate family amino acid, a proteinogenic amino acid, an aspartic acid and a L-alpha-amino acid. It is a conjugate acid of a L-aspartate(1-). It is an enantiomer of a D-aspartic acid.

Usage And Synthesis

Chemical Properties:

Apartic acid is an aliphatic monoaminodicarboxylic acid (amino acid) and is a well-known constituent of protein. It has a slight acid taste.

Aspartic acid Uses

It has a wide range of uses in medicine, food and chemical industry.

First, In medicine, it can be used to treat heart disease, liver disease, hypertension, and has the effect of preventing and restoring fatigue. Together with a variety of amino acids, it is made into amino acid infusion, used as an ammonia antidote, liver function promoter, and fatigue recovery Agent.

Second, In the food industry, it is a good nutritional supplement, added to various refreshing drinks; it is also the main raw material of sweetener (aspartame)-aspartame.

Third, In the chemical industry, it can be used as a raw material for the manufacture of synthetic resins. It can also be used as a nutritional additive in cosmetics.
