DL-Alanyl-Glycine is commonly used in biochemical research as a dipeptide model to study peptide bond formation, hydrolysis, and enzyme interactions. It serves as a substrate in enzymatic assays to investigate the activity of peptidases and proteases. In cell culture studies, it is utilized to examine amino acid transport mechanisms across cell membranes. Additionally, it finds application in the development of nutritional supplements and therapeutic formulations due to its role in protein synthesis and metabolic processes. Its stability and simplicity make it a valuable tool in peptide chemistry and pharmaceutical studies.
