Tryptophyl-Nε-t-butoxycarbonyl-lysyl-O-t-butylthreonine is a complex peptide compound consisting of three amino acids: tryptophan, lysine, and threonine. The tryptophan and lysine residues are connected through an amide bond, with the tryptophan's Nε atom forming a bond with the lysine's carboxyl group. The threonine residue is linked to the lysine through an ester bond, with the threonine's hydroxyl group forming a bond with the lysine's carboxyl group. The t-butoxycarbonyl (Boc) group is a protecting group attached to the Nε atom of the lysine, while the t-butyl (t-Bu) group is a protecting group attached to the hydroxyl group of the threonine. These protecting groups are crucial for preventing unwanted side reactions during peptide synthesis and are removed at specific stages of the process. tryptophyl-Nε-t-butoxycarbonyl-lysyl-O-t-butylthreonine is a building block in the synthesis of larger peptides and proteins, and its structure and properties are essential for understanding protein folding, stability, and function.
The CAS Registry Mumber 79385-73-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,3,8 and 5 respectively; the second part has 2 digits, 7 and 3 respectively. Calculate Digit Verification of CAS Registry Number 79385-73: (7*7)+(6*9)+(5*3)+(4*8)+(3*5)+(2*7)+(1*3)=182 182 % 10 = 2 So 79385-73-2 is a valid CAS Registry Number.
