Send EmailBeta Alanine, Beta Amino Propionic Acid, 107-95-9
Chemical Identity:
-
Name: Beta Alanine
-
Synonyms: Beta Amino Propionic Acid, 3-Aminopropionic Acid
-
CAS Number: 107-95-9
-
Molecular Formula: C₃H₇NO₂
-
Molecular Weight: 89.09 g/mol
-
Appearance: White crystalline powder
-
Solubility: Soluble in water
Functional Role:
-
Non-essential amino acid: Unlike essential amino acids, beta alanine is not directly incorporated into proteins.
-
Carnosine synthesis: It is the rate-limiting precursor for carnosine, a dipeptide found in skeletal muscle.
-
Buffering capacity: Carnosine helps buffer hydrogen ions (H⁺), delaying the onset of muscle fatigue during high-intensity exercise.
Applications.
-
Sports Nutrition:
-
Commonly included in pre-workout supplements.
-
Enhances endurance, reduces fatigue, and supports strength training.
-
-
Biochemical Research:
-
Used in studies of amino acid metabolism and muscle physiology.
-
-
Food Supplements:
-
Incorporated into formulations aimed at reducing fatigue and improving recovery.
-
Safety & Side Effects:
-
Typical effect: Temporary tingling or itching sensation (paresthesia), especially at higher doses.
-
Other possible effects: Mild gastrointestinal discomfort, headaches, or sleep disturbances in sensitive individuals.
-
Storage: Keep in a cool, dry place, tightly sealed container.
Natural Sources:
Although beta alanine itself is not abundant in foods, carnosine and related compounds are found in:
-
Red meat
-
Poultry
-
Fish
-
Dairy products
Summary: Beta Alanine (CAS 107-95-9) is a performance-enhancing amino acid derivative, primarily valued for its role in carnosine synthesis and muscle fatigue resistance. It is widely used in sports nutrition and pre-workout formulations, with a well-documented mechanism of action and a clear safety profile.
Beta Alanine – Sectoral Suitability Table
| Sector | Application Purpose | Suitability | Notes / Considerations |
|---|---|---|---|
| Sports Nutrition & Supplements | Increases muscle carnosine, delays fatigue, enhances performance | ✅ High suitability | Core pre-workout ingredient; must include paresthesia warning on labels |
| Functional Food Additives | Energy and recovery support, endurance enhancement | ⚠️ Moderate suitability | Claims must comply with food regulations; health claims limited |
| Pharmaceutical / Clinical Research | Studies on neuromuscular function, aging, muscle metabolism | ⚠️ Limited suitability | Requires GMP-grade purity; regulatory approval needed for clinical use |
| Animal Nutrition | Experimental performance and endurance support | ❌ Low suitability | Not widely used; lacks regulatory framework |
| Industrial Chemicals / R&D | Amino acid derivative for synthesis and laboratory research | ⚠️ Moderate suitability | Mainly for R&D purposes; limited commercial use outside sports nutrition |
| Cosmetics | Potential antioxidant and anti-aging properties | ⚠️ Limited suitability | Still experimental; not common in mainstream cosmetic formulations |
🔑 Key Points
