Asparagine

Description

What is Asparagine?

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.

L-asparagine is an optically active form of asparagine having L-configuration. It has a role as a nutraceutical, a micronutrient, a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite, a mouse metabolite and a plant metabolite. It is an aspartate family amino acid, a proteinogenic amino acid, an asparagine and a L-alpha-amino acid. It is a conjugate base of a L-asparaginium. It is a conjugate acid of a L-asparaginate. It is an enantiomer of a D-asparagine. It is a tautomer of a L-asparagine zwitterion. (Source: ChEBI)

Asparagine Uses

Asparagine is a non-essential amino acid that can be found in different food sources. It is also called aspartic acid and was first discovered in 1806. This amino acid is found in asparagus juice, and its name is derived from it. Since then, scientists have also found asparagine in many foods.

Dietary sources of asparagine include a large number of animal and plant foods. Some seafood, poultry and eggs also contain this amino acid. In addition, dairy products and cheese also contain small amounts of asparagine, and beef is also a good source of this amino acid.

In addition to asparagus, many plants also contain asparagine, such as rhizomes such as potatoes. Whole grains such as wheat and oats and legumes are also good sources. Many nuts also contain this amino acid. The body’s own production plus dietary intake, the body can usually obtain sufficient amounts of asparagine.

Although it is not an essential amino acid, there is no doubt that it has a positive effect on the body. The liver itself can produce this acid to help nourish the nervous system. Asparagine helps the nervous system maintain proper mood, and sometimes helps prevent excessive sensitivity to sound and touch. This amino acid also helps fight fatigue, so it can be used as a nutritional supplement for athletes. But so far, there are still controversies about the efficacy of asparagine.

When the liver cannot produce the proper amount of asparagine, the nervous system function will be negatively affected. This can be manifested by symptoms such as headache, irritability, forgetfulness, and even depression. Finding out the cause of liver dysfunction and treating it promptly can help alleviate these symptoms related to asparagine deficiency.
