Z-Asp(OBut)-Phe-NH2 is a synthetic peptide consisting of three amino acid residues: Z-protected aspartic acid (Asp), phenylalanine (Phe), and an amino-terminal amine group (NH2). The "Z" group is a benzyloxycarbonyl (Cbz) protecting group, which is commonly used in peptide synthesis to prevent unwanted side reactions. The "OBut" indicates that the aspartic acid side chain is protected with a tert-butyl ester group, which helps to stabilize the peptide during synthesis. This specific sequence of amino acids is often used in research to study peptide-protein interactions, drug design, and other biological applications. The structure of Z-Asp(OBut)-Phe-NH2 is designed to mimic natural peptides or to serve as a building block for the development of new therapeutic agents.

Check Digit Verification of cas no

The CAS Registry Mumber 5549-49-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,4 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5549-49:
(6*5)+(5*5)+(4*4)+(3*9)+(2*4)+(1*9)=115
115 % 10 = 5
So 5549-49-5 is a valid CAS Registry Number.

Synthesis and biological activity of CCK26-33-related analogues modified in position 31

Marseigne,Dor,Begue,Reibaud,Zundel,Blanchard,Pelaprat,Roques

, p. 966 - 970 (1988)

The role of the amino acid in position 31 of cholecystokinin CCK26-33 in the recognition of central and peripheral receptors was investigated by replacement of methionine-31 by amino acids with side chains of various chemical nature. Thus, phen
