(Fmoc-Cys-OtBu)2 (Disulfide bond) CAS:139592-37-3 is a small molecule that contains several functional groups. The Fmoc group is a type of protecting group commonly used in peptide synthesis. The Cys group refers to the amino acid cysteine, which contains a sulfhydryl (-SH) group that is important for the formation of disulfide bonds. The OtBu group is a protecting group for the thiol (-SH) group of cysteine. The disulfide bond refers to the covalent bond formed between two cysteine residues when their sulfhydryl groups are oxidized.
The disulfide bond is an important structural feature in many proteins, as it helps to stabilize the tertiary structure of the protein by forming covalent bridges between different regions of the polypeptide chain. In (Fmoc-Cys-OtBu)2 (Disulfide bond), the presence of two cysteine residues and the disulfide bond between them suggests that this molecule is likely a peptide or protein fragment that contains this important structural feature. The Fmoc and OtBu protecting groups, meanwhile, are used to protect the reactive functional groups during peptide synthesis, ensuring that the disulfide bond can be formed selectively and efficiently. Overall, (Fmoc-Cys-OtBu)2 (Disulfide bond) represents an important tool in the synthesis of peptides and proteins, and it is likely to have a range of applications in biochemistry, biotechnology, and pharmaceutical research.
