The substitution of the fluorine in place of hydrogen in building blocks, such as amino acids, has produced molecules with enhanced physiological activities (1-2). Some of these are antibacterial, antihypertensive and antitumoral (3). One reason for the enhanced activity is that fluorine forms a strong covalent bond with a carbon atom, which in peptides creates hyper-stable protein folds that render fluoro amino acid-containing peptides resistant to metabolic transformation (2, 4). The electronegativity of fluorine affects the pH of the neighboring groups, which in turn causes an overall change in the stability and reactivity of a molecule (2).

AnaSpec, a worldwide provider of integrated proteomics solutions, offers a wide collection of fluorinated amino acids.
