"Z-Tyr-D-Arg(Mts)-Gly-Phe-Met-NH2" is a synthetic peptide consisting of seven amino acids. It is characterized by the presence of a Z group, which is a protecting group used in peptide synthesis to prevent unwanted side reactions. The sequence includes D-Arg(Mts), where D stands for the D-configuration of the amino acid arginine, and Mts is a methanethiosulfonate group, which can be used to introduce a thiol-reactive group into the peptide. The other amino acids in the sequence are tyrosine (Tyr), glycine (Gly), phenylalanine (Phe), and methionine (Met). This specific sequence and the modifications may be designed for特定的生物活性或研究目的, such as studying receptor interactions, enzyme substrates, or as a component in drug design. The peptide's properties, such as solubility, stability, and biological activity, can be influenced by the presence of the Z group and the Mts modification, making it a potentially valuable tool in biochemical and pharmaceutical research.
The CAS Registry Mumber 76939-39-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,3 and 9 respectively; the second part has 2 digits, 3 and 9 respectively. Calculate Digit Verification of CAS Registry Number 76939-39: (7*7)+(6*6)+(5*9)+(4*3)+(3*9)+(2*3)+(1*9)=184 184 % 10 = 4 So 76939-39-4 is a valid CAS Registry Number.
