If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

General description
Moreover, L-Glutamine is essential for maintaining a delicate balance of ammonia in the body. This balance is crucial for preventing toxic ammonia levels. This amino acid facilitates the conversion of glutamic acid to glutamine, a process central to ammonia regulation. L-Glutamine is not only involved in nitrogen transport and energy production but also serves as a key player in various metabolic pathways. It participates in the biosynthesis of proteins, similar to other amino acids. Furthermore, it plays a significant role in the synthesis of urea and purines, vital components for nucleic acid production. L-Glutamine is also a vital resource for generating cellular energy, working closely with glucose for this purpose.
Another essential function of L-Glutamine is its contribution to nitrogen donation for multiple anabolic processes. These processes are vital for building crucial molecules, including purines, which are crucial for DNA production. This amino acid also provides carbon, replenishing the citric acid cycle, a central process in energy production within cells. L-Glutamine is a critical amino acid, acting as a nitrogen carrier, energy source, and contributing to protein synthesis and ammonia regulation. Its versatile functions make it a molecule of significant interest in the fields of cell biology, biochemical research, and metabolomics investigations.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
