詳細

アプリケーション

• Low-protein diet supplemented with 1% L-glutamine improves growth performance, serum biochemistry, redox status, plasma amino acids, and alters fecal microbiota in weaned piglets.: This study demonstrates how L-glutamine supplementation in a low-protein diet can significantly enhance growth metrics and overall health in weaned piglets (Li et al., 2024).


• Functionalization of β-cyclodextrin metal-organic frameworks with gelatin and glutamine for drug delivery of curcumin to cancerous cells.: This article covers the development of a novel drug delivery system using glutamine-modified frameworks for targeted cancer therapy (Sadeh et al., 2024).

生物化学的／生理学的作用

L-グルタミンは、培養細胞の主なエネルギー源となる重要な培地成分である必須アミノ酸です。L-グルタミンは、乾燥粉末および凍結溶液の状態で非常に安定です。しかし、液体培地やストック溶液において、L-グルタミンは比較的速く分解します。最適な細胞の性能には通常、使用前の培地へのL-グルタミンの添加が必要です。
