3,5-Bis(trifluoromethyl)-DL-phenylalanine (CAS 237076-69-6)

3,5-Bis(trifluoromethyl)-DL-phenylalanine is a synthetic amino acid derivative characterized by the substitution of two trifluoromethyl groups at the 3 and 5 positions on the phenyl ring of the phenylalanine molecule. This modification significantly alters the physicochemical properties of the molecule, making it an intriguing subject in the study of protein engineering and structure-function relationships in proteins. The incorporation of this fluorinated analog into peptides and proteins can lead to changes in hydrophobicity, steric bulk, and electronic effects, which in turn can affect the folding, stability, and overall conformation of the protein. These altered properties can be exploited to study protein interactions, folding pathways, and the effects of fluorine on biological systems. Additionally, the introduction of trifluoromethyl groups can influence the binding affinity of proteins to ligands, thereby serving as a useful tool in biochemical research focused on protein-ligand interactions. Research involving 3,5-Bis(trifluoromethyl)-DL-phenylalanine often aims to elucidate the roles of specific amino acid residues in proteins by substituting natural amino acids with this fluorinated analog, providing insights into the fundamental principles governing protein structure and function.
