Overview
Glycyl-L-glutamine monohydrate丨CAS 172669-64-6 is a dipeptide consisting of the amino acids glycine and L-glutamine, with one molecule of water of hydration. Dipeptides like Glycyl-L-glutamine are often studied and utilized for their biological significance, particularly in nutrition, cell culture, and peptide synthesis.
Applications
1. Nutritional and Pharmaceutical Use
Glycyl-L-glutamine serves as a nutritional supplement in clinical nutrition, especially in parenteral or enteral feeding formulations, due to its roles in:
Supporting nitrogen metabolism
Acting as a glutamine source, which is critical during stress, trauma, or illness when glutamine demand increases.
Used in studies focusing on gut health and mucosal protection since glutamine is vital for intestinal cell maintenance and repair.
2. Cell Culture and Biotechnology
Employed as a stable dipeptide substitute for L-glutamine in cell culture media.
Offers advantages over free glutamine by:
Reducing ammonia accumulation (a toxic byproduct from glutamine degradation).
Enhancing cell viability and growth in long-term cultures.
Supports protein synthesis and cellular metabolism effectively.
3. Peptide Synthesis and Research
Used as a building block in synthetic peptide chemistry.
Serves in biochemical assays to study peptide transport, metabolism, and enzymatic activity.
4. Pharmaceutical Research
Investigated for therapeutic roles in:
Wound healing
Immune support
Conditions requiring enhanced protein/nitrogen balance.
Summary
Glycyl-L-glutamine monohydrate丨CAS 172669-64-6 is a biologically relevant dipeptide widely used as a nutritional supplement, a cell culture additive, and a peptide research building block. Its stability and dual amino acid content provide advantages in clinical nutrition and biotechnology, especially where glutamine supplementation is critical.
