Z-L-Leu-L-Lys(Boc)-OH is a tripeptide, consisting of three amino acids: L-Leucine (L-Leu), L-Lysine (L-Lys), and a protected L-Lysine with a tert-butyloxycarbonyl (Boc) group. The "Z" group, or benzyloxycarbonyl, is a protecting group for the N-terminal amino group, which is crucial for preventing unwanted side reactions during peptide synthesis. This specific sequence is often used in the synthesis of larger peptides and proteins, as it can be a building block for more complex structures. The Boc group on L-Lysine is used to protect the epsilon amino group, which is essential for maintaining the peptide's structure and stability during synthesis. Once the desired peptide is formed, the Boc group can be removed to reveal the free amino group, allowing for further reactions or interactions. Z-L-Leu-L-Lys(Boc)-OH is a valuable component in the field of peptide chemistry, offering a protected and stable intermediate for the construction of biologically active molecules.
The CAS Registry Mumber 95049-84-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,0,4 and 9 respectively; the second part has 2 digits, 8 and 4 respectively. Calculate Digit Verification of CAS Registry Number 95049-84: (7*9)+(6*5)+(5*0)+(4*4)+(3*9)+(2*8)+(1*4)=156 156 % 10 = 6 So 95049-84-6 is a valid CAS Registry Number.
