Description:Boc-D-Cys(Acm)-OH, with the CAS number 138775-00-5, is a protected form of the amino acid cysteine, which is notable for its role in protein structure and function due to its thiol (-SH) group. The "Boc" (tert-butyloxycarbonyl) group serves as a protective group for the amino functionality, allowing for selective reactions without interfering with the amino group. The "D-Cys" indicates that this compound is the D-enantiomer of cysteine, which is less common than the L-form typically found in proteins. The "Acm" (acetylmethyl) group is another protective moiety that shields the thiol group, making it stable during synthesis and manipulation. This compound is often utilized in peptide synthesis and research, particularly in studies involving disulfide bond formation and redox reactions. Its characteristics include solubility in organic solvents, stability under standard laboratory conditions, and reactivity that can be tailored through deprotection strategies, making it a valuable intermediate in the synthesis of biologically active peptides and compounds.
