(FMOC-CYS-OTBU)2, (DISULFIDE BOND)

Description:
FMOC-CYS-OTBU, with the CAS number 139592-37-3, is a chemical compound that features a cysteine derivative modified with a fluorenylmethyloxycarbonyl (FMOC) protecting group and a tert-butyl (OTBU) group. This compound is characterized by the presence of a disulfide bond, which is formed between two cysteine residues, allowing for the stabilization of protein structures and influencing their biological activity. The FMOC group serves as a protective moiety that can be removed under specific conditions, facilitating the synthesis of peptides and proteins. The tert-butyl group enhances the solubility and stability of the compound in organic solvents. Overall, FMOC-CYS-OTBU is utilized in peptide synthesis and research, particularly in studies involving redox reactions and protein folding, due to its ability to form reversible disulfide bonds that play a crucial role in the tertiary structure of proteins.
