L-Alanyl-L-Glutamine

## L-Alanyl-L-Glutamine (Ala-Gln, CAS 39537-23-0): Key Functions and Uses

1. **Stable Glutamine Dipeptide**
L-Alanyl-L-Glutamine, also known as **alanyl-glutamine or Ala-Gln**, is a dipeptide composed of L-alanine and L-glutamine. Its stable and water-soluble structure makes it useful as an alternative source of glutamine in nutritional and biochemical formulations.

2. **Clinical and Parenteral Nutrition**
CAS 39537-23-0 is used in specialized enteral and parenteral nutrition research. It can provide glutamine and alanine during the preparation of nutritional solutions, particularly when formulation stability and solubility are important.

3. **Support for Intestinal and Metabolic Research**
L-Alanyl-L-Glutamine is investigated for its role in maintaining intestinal barrier function, nitrogen metabolism, cellular energy supply, and tissue-support pathways. Its effects depend on dosage, administration route, patient condition, and the complete nutritional formulation.

4. **Cell-Culture and Biopharmaceutical Applications**
Ala-Gln is widely used in cell-culture media and bioprocessing research. It can serve as a more stable glutamine source for mammalian cell culture, recombinant protein production, vaccine research, antibody development, and other biopharmaceutical workflows.

5. **Amino-Acid and Protein-Metabolism Research**
After utilization or hydrolysis, the dipeptide provides L-glutamine and L-alanine for biochemical pathways. Researchers use it to study amino-acid transport, protein synthesis, nitrogen utilization, cell proliferation, and cellular stress responses.

6. **Nutritional Supplement and Sports-Nutrition Research**
L-Alanyl-L-Glutamine may be included in nutritional and sports-research formulations designed to deliver glutamine in a stable dipeptide form. Commercial product claims should be supported by formulation data, applicable regulations, and appropriate clinical evidence.

7. **Quality and Procurement Considerations**
When sourcing L-Alanyl-L-Glutamine 39537-23-0, buyers should verify peptide purity, assay, stereochemical identity, water content, residual solvents, microbial limits, endotoxin specifications where relevant, packaging, and certificate of analysis. Useful SEO keywords include **L-Alanyl-L-Glutamine, Ala-Gln, alanyl-glutamine dipeptide, CAS 39537-23-0, clinical nutrition ingredient, cell-culture supplement, parenteral nutrition, biopharmaceutical reagent, and glutamine source**.
