This dipeptide, composed of isoleucine and tryptophan, is primarily used in biochemical research and pharmaceutical development as a building block for synthesizing larger peptides or proteins. It aids in the study of peptide structure, function, and folding. The specific Ile-Trp sequence is valuable for investigating biological processes, including enzyme-substrate interactions, receptor binding, and potential antimicrobial or sensory properties in food science. It is also utilized in drug discovery for designing peptide-based therapeutics and in studies of metabolic pathways and signal transduction.
