一般描述

L-谷氨酰胺被发现是血流中最丰富的氨基酸之一。 它可用于许多生物化学过程，如生产其他氨基酸、葡萄糖、核苷酸、蛋白质和谷胱甘肽。 它还可以用作增加肠绒毛高度、维持粘膜完整性和刺激肠粘膜细胞增殖的补充剂。 由于它具有抑制肠道和口腔毒性副作用的功能，它还可以应用于化学疗法和放射疗法的治疗中。
该有证标准物质（CRM）是根据ISO/IEC 17025和ISO 17034生产和认证的。该CRM可追溯到来自NMI的原材料，如 NIST或NMIJ。
证书上给出了定量核磁共振法认证的内容，包括不确定性和失效日期。

生化/生理作用

L-谷氨酰胺是一种必需氨基酸，作为细胞培养过程中主要的能量来源而成为培养基的重要组分。L-谷氨酰胺在干粉及冷冻溶液的状态下极为稳定。然而，L-谷氨酰胺在液体培养基或储存溶液中均会相对较快的降解。最佳的细胞表现通常需要在使用前向培养基中添加L-谷氨酰胺补充剂。

Failure of cytotoxic T lymphocytes (CTLs) or natural killer (NK) cells to kill target cells by perforin (Prf)/granzyme (Gzm)-induced apoptosis causes severe immune dysregulation.
