Z-Tyr-D-MeAla-Gly-OH is a synthetic tetrapeptide, consisting of four amino acid residues: Z-Tyr (N-benzyloxycarbonyl-tyrosine), D-MeAla (D-methionine sulfoxide), and Gly (glycine). This peptide is characterized by its unique arrangement of amino acids, with Z-Tyr being a derivative of the naturally occurring amino acid tyrosine, featuring a protecting group that shields the carboxyl group during peptide synthesis. D-MeAla is a non-natural, D-enantiomeric form of methionine, with an additional sulfur atom in the form of a sulfoxide group. The presence of these modified amino acids gives Z-Tyr-D-MeAla-Gly-OH distinct chemical and biological properties compared to naturally occurring peptides. This synthetic peptide has potential applications in drug development, as it can be used to study the interactions between peptides and their targets, as well as to develop new therapeutic agents with specific biological activities.
The CAS Registry Mumber 81378-75-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,7 and 8 respectively; the second part has 2 digits, 7 and 5 respectively. Calculate Digit Verification of CAS Registry Number 81378-75: (7*8)+(6*1)+(5*3)+(4*7)+(3*8)+(2*7)+(1*5)=148 148 % 10 = 8 So 81378-75-8 is a valid CAS Registry Number.
