Z-Ala-Phe-Ile-Ala-NH2 is a synthetic peptide consisting of five amino acids: Z-protected alanine (Z-Ala), phenylalanine (Phe), isoleucine (Ile), another alanine (Ala), and a terminal amide group (NH2). The "Z" in Z-Ala refers to the benzyloxycarbonyl group, which is a protecting group used in peptide synthesis to prevent unwanted side reactions. This peptide is often used as a model system in studies of protein folding, enzymatic activity, and as a substrate for proteases. It serves as a simplified representation of a segment of a larger protein, allowing researchers to investigate the properties of peptides and their interactions with other molecules under controlled conditions.

Check Digit Verification of cas no

The CAS Registry Mumber 87831-93-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,8,3 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 87831-93:
(7*8)+(6*7)+(5*8)+(4*3)+(3*1)+(2*9)+(1*3)=174
174 % 10 = 4
So 87831-93-4 is a valid CAS Registry Number.

The 2-Thiosulfatoethyl Group as Solubilizing Protective Group in Enzymatic Peptide Synthesis

Kuhl, P.,Walpuski, J.,Jakubke, H.-D.

, p. 465 - 466 (2007/10/02)

Amino acid (2-thiosulfatoethyl esters) 4 can be prepared from amino acid (2-chloroethyl esters) by nucleophilic exchange of halogen for thiosulfate.Coupling of the esters 4 with Z-protected amino acids gives the water-soluble Z-dipeptide esters 5 which re

Protease-catalyzed (2+2)-Segment Condensation in an Aqueous-Organic Two-phase System

Kuhl, P.,Doering, G.,Jakubke, H.-D.

, p. 371 - 372 (2007/10/02)

Tetrapeptides Z-Ala-Phe-X-Ala-NH2 can be prepared in good yields by α-chymotrypsin-catalyzed reactions of Z-Ala-Phe-OMe and X-Ala-NH2 in an aqueous-organic two-phase system using CCl4 as solvent.This method is also advantageous for the synthesis of Boc-Al
