Used in peptide synthesis as a building block for creating specific peptide sequences. It helps in modifying peptides to enhance their stability, bioavailability, or biological activity. Commonly applied in pharmaceutical research for developing therapeutic peptides. Also utilized in biochemical studies to investigate protein interactions and functions. Its isopropyl group can influence the peptide's hydrophobicity, making it useful in designing peptides with tailored properties for drug delivery or targeting specific biological pathways.
