Application
- 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).
