Using the two
iron catalysts, the researchers were able to take four chiral amino acids — proline, leucine, valine and norvaline — and diversify them into 21 different amino acid structures while preserving their
handedness.
Now, researchers have demonstrated that two
iron - containing small - molecule catalysts can help turn certain types of amino acids — the building blocks of peptides and proteins — into an array of potential new forms, even when part of a larger peptide, while preserving a crucial aspect of their chemistry: chirality, or «
handedness.»
