CAS 135248-89-4: L-Cysteine, N-[(9H-fluoren-9-ylmethoxy)carbonyl]-

Description:L-Cysteine, N-[(9H-fluoren-9-ylmethoxy)carbonyl]- is a derivative of the amino acid L-cysteine, which is known for its role in protein synthesis and as a precursor to the antioxidant glutathione. This compound features a protective fluorenylmethoxycarbonyl (Fmoc) group, commonly used in peptide synthesis to temporarily protect the amino group of amino acids. The presence of the Fmoc group enhances the stability and solubility of L-cysteine during chemical reactions, facilitating its incorporation into peptides. L-Cysteine itself is characterized by a thiol (-SH) group, which contributes to its reactivity and ability to form disulfide bonds, playing a crucial role in maintaining protein structure. The compound is typically utilized in biochemical research and peptide synthesis, where it can be deprotected to yield free L-cysteine for further applications. Overall, this substance combines the properties of L-cysteine with the advantages of the Fmoc protecting group, making it valuable in synthetic organic chemistry and biochemistry.
