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
さらに、L-グルタミンは、体内アンモニアの微妙なバランスを維持するために不可欠です。このバランスは、有毒なアンモニアレベルを避けるために重要です。このアミノ酸は、アンモニア調節の中心となるプロセスである、グルタミン酸のグルタミンへの変換を促進します。L-グルタミンは、窒素輸送とエネルギー産生に関与するだけでなく、さまざまな代謝経路において重要な役割を果たします。他のアミノ酸と同じように、タンパク質の生合成に関与します。さらに、核酸の産生に必須の成分である尿素とプリンの合成で重要な役割を果たします。また、L-グルタミンは、細胞エネルギーの生成に不可欠なリソースでもあり、グルコースと密接に連携することによりその目的を果たします。
L-グルタミンのその他の重要な機能には、複数の同化作用への窒素供給に対する貢献があります。これらの作用は、プリンなどの重要な分子を構成するために不可欠であり、DNA産生にとって重要です。このアミノ酸は炭素も供給し、細胞内エネルギー産生の中心的なプロセスであるクエン酸回路を活性化します。L-グルタミンは、窒素担体やエネルギー源として機能し、さらにタンパク質合成とアンモニア調節に寄与する重要なアミノ酸です。このような多様な機能から、細胞生物学、生化学、およびメタボロミクスの研究分野において大きな関心を集める分子となっています。

How is shipping temperature determined? And how is it related to the product storage temperature?
1 回答-
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

Is the molecular weight of L-Glutamine 146.14 or 146.15? The label information changed.
1 回答-
Based on a molecular formula of C5H10N2O3, the molecular weight to seven significant figures is 146.1456. Over the years, this value may have been reported in Sigma-Aldrich documentation or on labels as either 146.15 (by rounding up) or 146.14 (by truncation). The material itself has not changed.
