Product Description
L-Alanyl-L-Glutamine CAS 39537-23-0
L-Alanyl-L-Glutamine (CAS 39537-23-0) is a highly stable, bioavailable dipeptide composed of L-alanine and L-glutamine. It serves as an efficient source of glutamine, overcoming the instability limitations of free glutamine in solutions. Widely used in clinical nutrition, sports supplements, and cell culture media, this compound supports immune function, gut health, muscle recovery, and cellular energy.

Product Functions
- Enhanced Stability: More stable than free glutamine in aqueous solutions and during heat processing
- Improved Bioavailability: Rapidly hydrolyzed in the body to release L-glutamine and L-alanine
- Muscle Recovery: Supports protein synthesis, reduces muscle breakdown, and aids post-exercise recovery
- Immune Support: Provides glutamine for immune cell function and intestinal integrity
- Gut Health: Promotes mucosal repair and maintains gut barrier function
- Cell Culture Applications: Serves as a stable glutamine source in cell media, avoiding ammonia accumulation
- Antioxidant & Metabolic Support: Participates in glutathione synthesis and energy production
Application Areas
- Clinical Nutrition: Used in parenteral and enteral nutrition for critically ill, surgical, and trauma patients
- Sports Nutrition: Added to recovery drinks, protein powders, and endurance supplements
- Dietary Supplements: Capsules, tablets, and powders for immune and gut health formulations
- Pharmaceuticals: Raw material for injectables, infusion solutions, and regenerative medicine
- Cell Culture & Bioprocessing: Component of media for mammalian cell culture, vaccine production, and biomanufacturing
- Functional Foods & Beverages: Fortified in health drinks, meal replacements, and medical foods
- Veterinary Products: Used in animal nutrition for performance, recovery, and health support
