(S)-N-Fmoc-L-norleucine-13C6,15N

(S)-N-Fmoc-L-norleucine-13C6,15N is a chemical compound that is commonly used in the field of peptide synthesis. It is a derivative of norleucine, an amino acid that is not found in natural proteins. The compound is often used as a building block in the synthesis of peptides, which are chains of amino acids that are linked together through peptide bonds. The (S)-N-Fmoc-L-norleucine-13C6,15N molecule contains six carbon atoms and fifteen nitrogen atoms, which are isotopically labeled with the stable isotopes of carbon and nitrogen. This labeling allows researchers to use techniques such as NMR spectroscopy to study the structure and behavior of peptides that incorporate this compound. The Fmoc group attached to the norleucine molecule is a protecting group that can be easily removed using base-catalyzed deprotection. This allows the norleucine residue to be incorporated into the peptide chain without interfering with the peptide synthesis process. Overall, (S)-N-Fmoc-L-norleucine-13C6,15N is a valuable tool for researchers in the field of peptide synthesis, allowing them to study the structure and behavior of peptides in more detail. Its isotopically labeled carbon and nitrogen atoms make it particularly useful for NMR studies, while the Fmoc protecting group allows for easy incorporation into peptide chains.
