L-Alanyl-glycine is widely used in the pharmaceutical and biotechnology industries as a dipeptide model for studying enzyme mechanisms and peptide interactions. It serves as a substrate in enzymatic assays to understand the activity of proteases and peptidases. In cosmetic formulations, it acts as a moisturizing agent, helping to improve skin hydration and elasticity. Additionally, it is utilized in nutritional supplements to support muscle recovery and enhance protein synthesis. Its stability and biocompatibility make it a valuable component in research and development for drug delivery systems.
