Asparagine is a non-essential protein amino acid that is present in many fruits and vegetables including asparagus, from which it gets its name. Other dietary sources include meat, potatoes, eggs, nuts, and dairy. It can also be formed from aspartic acid and glutamine using the enzyme asparagine synthetase.

In addition to being a structural component of many proteins, asparagine is also useful to the urea cycle. It acts as a nontoxic carrier of residual ammonia to be eliminated from the body. Asparagine is rapidly converted to aspartic acid by the enzyme asparaginase. Interestingly, L-asparaginase has been successfully used as a chemotherapeutic agent for decades.

It causes extracellular depletion of asparagine which seems to play a critical role in cellular adaptations to glutamine and apoptosis.

Asparagine is a protein amino acid. It is non-essential in humans, meaning the body can synthesize it.

Asparagine is synthesized from aspartate and glutamine. Asparagine has three major functions:

1. incorporation into amino acid sequences of proteins
2. storage form for aspartate (is a required precursor for synthesis of DNA, RNA and ATP)
3. source of amino groups for production of other dispensable amino acids via Transaminases.

Asparagine is a non-essential amino acid required for development and function of the brain. Asparagine can be synthesized from glutamine and aspartate. Asparagine is also required for DNA and RNA synthesis and removal of the cellular waste product ammonia.

Aspartic acid is a nonessential amino acid that plays roles in many important metabolic processes, such as energy production (citric acid cycle), hormone metabolism, CNS activation, and the urea cycle. It is found in many protein sources such as oysters, meats, seeds, avocado, asparagus, and beets. It is also an ingredient in artificial sweeteners.

Aspartic acid is a precursor to many amino acids and other molecules like asparagine, arginine, isoleucine, lysine, methionine, isoleucine, threonine, nucleotides, NAD, and pantothenate. Aspartate, like glutamine, can also be considered a neuroexcitatory neurotransmitter since it activates the N-methyl-D-aspartate receptor in the brain.

Aspartate-aminotransferase (AST) and alanine-aminotransferase (ALT) are both produced by the liver and serve in functions throughout the human body. Aspartate-aminotransferase is most commonly related to liver health. Blood tests for AST and ALT are often ordered together to identify the source of damage in our organs. 

AST is an intracellular enzyme that is usually elevated due to active tissue and cellular destruction. May be elevated due to hepatitis, liver cirrhosis or alcoholism, hypothyroidism. May be decreased due to Vit B6 deficiency, elevated serum nitrogen.

Asparagine is converted to aspartic acid, then to glutamic acid.

Asparagine is a nontoxic carrier of residual ammonia. A byproduct of asparagine metabolism is oxaloacetate.

Higher levels of asparagine were associated with lower rates of diabetes, insulin, and HOMA.

Plasma asparagine and the tyrosine/phenylalanine ratio were found to be protective against depression.

Higher asparagine, aspartic acid, and citrulline were associated with higher rates of physical frailty and sarcopenia.

Plasma glutamine, cysteine, and asparagine were significantly downregulated in psoriasis patients.
