Chemical Structure



Fmoc-D-Cys(4-MeBzl)-OH is a valuable building block in chemical synthesis, particularly in the field of peptide synthesis. Due to its unique structure, it allows for precise control over the positioning of cysteine residues within peptide sequences. This specific derivative of cysteine, known for its Fmoc (Fluorenylmethyloxycarbonyl) protection group and 4-Methylbenzyl side chain, offers enhanced stability during peptide assembly and manipulation processes.In peptide synthesis, Fmoc-D-Cys(4-MeBzl)-OH plays a crucial role in introducing cysteine residues at specific locations within the peptide chain. The Fmoc protection group ensures selective deprotection under mild conditions, enabling stepwise assembly of complex peptide sequences. Additionally, the 4-Methylbenzyl side chain provides additional protection and can be selectively removed when needed to allow for further chemical modifications.Overall, the application of Fmoc-D-Cys(4-MeBzl)-OH in chemical synthesis offers chemists precise control over cysteine incorporation in peptide design, making it a versatile tool for the development of custom peptides with specific functionalities.
