This dipeptide, consisting of valine and isoleucine, is primarily used in biochemical research to study peptide interactions, enzyme mechanisms, and protein folding. It serves as a building block in peptide synthesis, enabling the creation of larger, more complex peptides for therapeutic or experimental purposes. Additionally, it is utilized in nutritional science to explore the role of specific amino acid sequences in dietary supplements and their impact on muscle repair and growth. Its application extends to the development of bioactive peptides with potential health benefits, such as immune modulation or metabolic regulation.
