"Z-(L)-Trp-(D)-Trp-(L)-Pro-PNP" is a synthetic peptide consisting of four amino acids: (L)-tryptophan, (D)-tryptophan, (L)-proline, and a p-nitrophenyl (PNP) group. The "Z" prefix indicates the presence of a carbobenzoxy (Cbz) protecting group, which is commonly used in peptide synthesis to prevent unwanted side reactions. This specific sequence of amino acids is designed to mimic certain biologically active peptides, and the PNP group serves as a reporter for enzymatic activity, allowing for the detection and quantification of specific proteases or other enzymes that can cleave the peptide. The chirality of the amino acids, with a mix of L (levo) and D (dextro) configurations, is crucial for the peptide's structure and function, as enzymes often exhibit strict stereospecificity. Z-(L)-Trp-(D)-Trp-(L)-Pro-PNP is valuable in research settings for studying enzyme specificity, kinetics, and mechanisms.

Check Digit Verification of cas no

The CAS Registry Mumber 82989-15-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,9,8 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 82989-15:
(7*8)+(6*2)+(5*9)+(4*8)+(3*9)+(2*1)+(1*5)=179
179 % 10 = 9
So 82989-15-9 is a valid CAS Registry Number.

STEREOSELECTIVITY IN MICELLAR AND VESICULAR REACTIONS

Moss, Robert A.,Taguchi, Takayuki,Bizzigotti, George O.

, p. 1985 - 1988 (2007/10/02)

The diastereoselectivity of esterolytic cleavage of certain dipeptide and tripeptide activated esters is lower in thio-functionalized vesicles than in comparable micelles.This is thought to be a mechanism-specific effect related to the greater molecular o
