Applications

 

 

1. Pharmaceutical Industry

Nutritional Supplements: Used as a source of cystine and alanine in amino acid supplements, supporting protein synthesis and antioxidant defense.

Antioxidant Support: Cystine is a precursor of cysteine, which in turn is essential for glutathione synthesis, a critical intracellular antioxidant. Thus, L-Alanyl-L-Cystine may help in maintaining cellular redox balance.

Wound Healing: Supports tissue repair processes due to its role in collagen synthesis and sulfur metabolism.

Drug Formulations: Utilized in peptide-based formulations and as a stabilizing agent in certain pharmaceutical products.

2. Cosmetic and Personal Care

Hair Care Products: As cystine is a key component of keratin, L-Alanyl-L-Cystine is used in hair care formulations to promote hair strength and repair damaged hair fibers.

Skin Care: Contributes to skin elasticity and protection against oxidative stress, often included in anti-aging and repair creams.

3. Food and Nutrition

Functional Food Ingredient: Incorporated into specialized nutritional formulas aimed at supporting muscle recovery, antioxidant status, and sulfur amino acid intake.

Protein Fortification: Enhances the amino acid profile of protein supplements, especially for individuals with increased demand for sulfur amino acids.

04

Benefits

 

Stable Source of Sulfur Amino Acids: Provides cystine in a form resistant to oxidation, enhancing bioavailability.
