One aspect of the invention relates to hexafluoroleucine and congeners thereof, and methods of making the compounds. Another aspect of the nvention relates to the synthesis of protein cores comprising hexafluoroleucine and congeners thereof. Certain peptides comprising hexafluorleucine and congeners thereof have been characterized using comparative biophysical studies. In general, the fluorinated peptides show higher thermal stability and enhanced resistance to chemical denaturation. Further, mixed hydrocarbonfluorocarbon cores self-sort into homogeneous bundles, suggesting new avenues for the design and manipulation of protein-protein interfaces.

One aspect of the invention relates to a polypeptide comprising at least one fluorinated amino acid. Another aspect of the invention relates to a method for modifying a first polypeptide, comprising replacing at least one amino acid in said first polypeptide with a fluorinated amino acid, thereby producing a second polypeptide with increased stability relative to said first polypeptide.
