Introduction: L-glutamine (chemical formula: C5H10N2O3) is an alpha-amino acid that is one of the 20 amino acids consisting proteins. L-glutamine is a non-essential amino acids and is also the most abundant amino acids in human bodies. It is involved in many important biological processes. For example, it is a building block for the protein synthesis as one key amino acid; it is used in the biosynthesis of urea and purines for nucleic acid synthesis; it is a substrate for the biosynthesis of neurotransmitters; it is also an important sources of cellular energy generation. L-glutamine provides many benefits to the body such as improving gastrointestinal health, aiding the treatment of ulcer and leaky gut, promoting muscle growth, improving diabetes and blood sugar as well as aiding in the treatment of cancer.

3.3 Usage
L-Glutamine is an essential amino acid that is a crucial component of culture media that serves as a major energy source for cells in culture. L-Glutamine is very stable as a dry powder and as a frozen solution. In liquid media or stock solutions, however, L-glutamine degrades relatively rapidly. Optimal cell performance usually requires supplementation of the media with L-glutamine prior to use.

8.1 Description
Glutamine (abbreviated as Gln or Q) is one of the 20 amino acids encoded by the standard genetic code. It is not recognized as an essential amino acid, but may become conditionally essential in certain situations, including intensive athletic training or certain gastrointestinal disorders.Its side-chain is an amide formed by replacing the side-chain hydroxyl of glutamic acid with an amine functional group, making it the amide of glutamic acid. Its codons are CAA and CAG. In human blood, glutamine is the most abundant free amino acid, with a concentration of about 500–900 μmol / l .
8.2 Chemical Properties
White crystalline powder
8.3 Chemical Properties
White, odorless crystals or crystalline powder having a slightly sweet taste. It is soluble in water and practically insoluble in alcohol and in ether. Its solutions are acid to litmus. It melts with decomposition at about 185°C.
8.4 Chemical Properties
L-glutamine is odorless, but has a slightly sweet taste L-glutamine performs a major role in DNA synthesis and sup- ports the immune system by means of glutathione synthesis.
8.5 Occurrence
Occurrences in nature
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.In the body, it is found circulating in the blood, as well as stored in the skeletal muscles. It becomes conditionally essential (requiring intake from food or supplements) in states of illness or injury.Dietary sources
Dietary sources of L-glutamine include beef, chicken, fish, eggs, milk, dairy products, wheat, cabbage, beets, beans, spinach, and parsley. Small amounts of free L-glutamine are also found in vegetable juices.
Aiding gastrointestinal functionGlutamine-enriched diets have been linked with maintenance of gut barrier function and cell differentiation, suggesting glutamine may help to protect the lining of the gastrointestinal tract or mucosa. People who have inflammatory bowel disease (ulcerative colitis and Crohn' s disease) may not have enough glutamine, but two clinical trials found taking glutamine supplements did not improve symptoms of Crohn' s disease.

8.14 General Description
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. L-glutamine is the most abundant amino acid in the body. It is essential for the synthesis of L-asparagine. It also helps in muscle growth through protein synthesis and increased growth hormone levels.

8.18 Usage
L-Glutamine is involved in many metabolic processes and regulates acid-base balance in the kidney. It is an important amino acid for the incorporation of ammonium ions into biomolecules. It is a vital component of culture media that serves as a major energy source for cells in culture. As a component in oral supplementation, it is useful for patients who have advanced stages of cancer to reverse cachexia (i.e. muscle wasting). It is also used for attention deficit-hyperactivity disorder (ADHD), a urinary condition called cystinuria, sickle cell anemia and for alcohol withdrawal support. It finds applications in patients with HIV (AIDS) to prevent weight loss.
