Why is glutamine prescribed?

Glutamine is marketed as medical food and is prescribed when a medical professional believes a person in their care needs supplementary glutamine due to metabolic demands beyond what can be met by endogenous synthesis or diet.

What is the most abundant amino acid in the human body?

Glutamine is the most abundant naturally occurring, nonessential amino acid in the human body, and one of the few amino acids that can directly cross the blood–brain barrier. Humans obtain glutamine through catabolism of proteins in foods they eat.

What are the functions of glucose?

Glutamine plays a role in a variety of biochemical functions: Protein synthesis, as any other of the 20 proteinogenic amino acids. Lipid synthesis, especially by cancer cells. Regulation of acid-base balance in the kidney by producing ammonium. Cellular energy, as a source, next to glucose.

What foods contain glutamine?

The dietary sources of glutamine includes especially the protein-rich foods like beef, chicken, fish, dairy products, eggs, vegetables like beans, beets, cabbage, spinach, carrots, parsley, vegetable juices and also in wheat, papaya, Brussels sprouts, celery, kale and fermented foods like miso .

How is glutamine made?

Glutamine is produced industrially using mutants of Brevibacterium flavum, which gives ca. 40 g/L in 2 days using glucose as a carbon source. Glutamine is synthesized by the enzyme glutamine synthetase from glutamate and ammonia. The most relevant glutamine-producing tissue is the muscle mass, accounting for about 90% of all glutamine synthesized. Glutamine is also released, in small amounts, by the lungs and brain. Although the liver is capable of relevant glutamine synthesis, its role in glutamine metabolism is more regulatory than producing, since the liver takes up large amounts of glutamine derived from the gut.

Where is glutamine released?

Glutamine is also released, in small amounts, by the lungs and brain. Although the liver is capable of relevant glutamine synthesis, its role in glutamine metabolism is more regulatory than producing, since the liver takes up large amounts of glutamine derived from the gut.

What is glutamic acid?

Glutamic Acid. Glutamic acid is an acidic, hydrophilic amino acid. As the amino acid, glutamic acid has important roles as a neurotransmitter and a flavor component. In peptides, glutamic acid residues may be utilized to form cyclic structures through amide bond formation with a lysine residue side chain.

What is the only amino acid that incorporates the Î-amine into a ring?

Proline is the only natural amino acid that incorporates the α-amine into a ring. Because of this unique structure, proline residues introduce a “kink” into the backbone structure of peptides. Proline disrupts β-sheet formation and promotes turn formation. This property of the proline residue is exploited in pseudoproline derivatives utilized to disrupt peptide aggregation and product higher yield and higher purity peptides with difficult sequences. (See the Pseudoproline Dipeptide section for AAPPTec’s pseudoproline products). Since proline does not contain a primary amine, Kaiser test (ninhydrin test) results may give false positive results when testing coupling to proline. Alternative tests, such as the 2,4,6-trinitobezoic acid test, should be considered.

What is arginine amino acid?

Arginine is a basic, hydrophilic amino acid . The guanidinium group in the sidechain is strongly basic and is protonated in most conditions. Arginine is a common component of cell-penetrating peptides which are utilized to transport larger molecules and particles into cells. In proteins, arginine can play a regulatory role. Arginine residues may be mono- or di-methylated on the sidechain or may be converted to citrulline. Regulatory modifications of arginine residues are often observed in histone proteins. AAPPTec offers a variety of high purity Fmoc or Boc protected arginine derivatives for solid phase peptide synthesis. AAPPTec also provides many high quality arginine derivatives for solution phase synthesis.

Which amino acid is a nucleophile?

Histidine. Histidine is a mildly basic, moderately hydrophobic amino acid. Histidine residues often play important roles in enzymes. The histidine side chain can activate serine, threonine or cysteine residues as nucleophiles by abstracting a proton.

Is alanine a hydrophobic amino acid?

Alanine is the simplest optically active amino acid. It is nonpolar and contributes a hydrophobic character when incorporated into a peptide, although the unprotected amino acid is water soluble. Alanine is a strong α-helix forming amino acid and does not significantly contribute to turn or β-sheet formation. AAPPTec provides Fmoc, Boc, and Z protected alanine as well as alanine esters with 99+% purity. High purity amino acid derivatives from AAPPTec produce higher peptide yields and purer peptides.

Is glycine a peptide?

Glycine is the simplest amino acid. It lacks a sidechain, thus is achiral. As a free amino acid, glycine is very water soluble due to its small size and strong hydrogen bonding ability of the acid and amine functions. Incorporated into a peptide, glycine contributes a small hydrophobic character to the peptide.

Does glutamine cyclize?

As an N-terminal residue, glutamine can cyclize to form pyroglutamic acid. Glutamine, like aspargine, is susceptible to nitrile formation by dehydration. As with asparagine, side-chain protection blocks this side reaction in increases the solubility of the derivative in organic solvents.

Uses

Glutamine is the most abundant naturally occurring, nonessential amino acid in the human body, and one of the few amino acids that can directly cross the blood–brain barrier. Humans obtain glutamine through catabolism of proteins in foods they eat.

Safety

Glutamine is safe in adults and in preterm infants. Although glutamine is metabolized to glutamate and ammonia, both of which have neurological effects, their concentrations are not increased much, and no adverse neurological effects were detected. The observed safe level for supplemental L-glutamine in normal healthy adults is 14 g/day.
Adverse effects of glutamine have been prescribed for people receiving home parenteral nutritio…

Structure

Glutamine can exist in either of two enantiomeric forms, L-glutamine and D-glutamine. The L-form is found in nature. Glutamine contains an α-amino group which is in the protonated −NH3 form under biological conditions and a carboxylic acid group which is in the deprotonated −COO form, known as carboxylate, under physiological conditions.
