Fmoc-a-Me-Cys(Trt)-OH

Description:
Fmoc-a-Me-Cys(Trt)-OH, with the CAS number 725728-43-8, is a protected amino acid derivative commonly used in peptide synthesis. The "Fmoc" (9-fluorenylmethoxycarbonyl) group serves as a protective moiety for the amino group, allowing for selective reactions during peptide assembly. The "a-Me" indicates the presence of a methyl group on the alpha carbon, which can influence the steric and electronic properties of the amino acid. The "Cys" refers to cysteine, an amino acid known for its thiol (-SH) side chain, which can form disulfide bonds, contributing to the stability and structure of peptides. The "Trt" (trityl) group is a protective group for the thiol side chain, preventing unwanted reactions during synthesis. Overall, Fmoc-a-Me-Cys(Trt)-OH is valuable in the field of peptide chemistry for its ability to facilitate the synthesis of complex peptides while maintaining the integrity of reactive functional groups. Its unique structural features make it suitable for various applications in drug development and biochemistry.
