Z-Glu(t-Bu)-Lys(Boc)-OMe is a peptide compound consisting of three amino acids: glutamic acid (Glu), lysine (Lys), and methionine (Met), with specific protecting groups. The glutamic acid is in the Z configuration, which refers to the stereochemistry of the amino acid side chain. The t-Bu group is a tert-butyl group, a type of protecting group used in peptide synthesis to prevent unwanted side reactions. The Boc group is a tert-butyloxycarbonyl group, another protecting group that shields the amino group of lysine. The OMe group indicates that the peptide is capped with a methoxy group, which can be used to terminate the peptide chain or as a protecting group for the carboxyl group. Z-Glu(t-Bu)-Lys(Boc)-OMe is used in the synthesis of peptides and proteins, where the protecting groups are crucial for controlling the reaction conditions and preventing unwanted side reactions, ensuring the correct sequence and structure of the final product.
The CAS Registry Mumber 73337-32-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,3,3 and 7 respectively; the second part has 2 digits, 3 and 2 respectively. Calculate Digit Verification of CAS Registry Number 73337-32: (7*7)+(6*3)+(5*3)+(4*3)+(3*7)+(2*3)+(1*2)=123 123 % 10 = 3 So 73337-32-3 is a valid CAS Registry Number.
