The chemical sequence "Z-Glu(OBut)-Ala-Tyr-Ile-Pro-Lys(Boc)-Glu(OBut)-Gln-Lys(Boc)-Tyr-Ser-Phe-OBut" represents a peptide, which is a chain of amino acids. In this sequence, each three-letter abbreviation corresponds to a specific amino acid: Glu for glutamic acid, Ala for alanine, Tyr for tyrosine, Ile for isoleucine, Pro for proline, Lys for lysine, Gln for glutamine, and Ser for serine, Phe for phenylalanine. The "Z" and "Boc" groups are protecting groups used in peptide synthesis to prevent unwanted side reactions. "Z" (benzyloxycarbonyl) is a group that protects the amino group of the first amino acid, while "Boc" (tert-butoxycarbonyl) protects the amino group of lysine. The "OBut" (tert-butyloxycarbonyl) groups protect the side chain carboxyl groups of glutamic acid and serine, preventing them from participating in unwanted reactions during peptide synthesis. This specific sequence of amino acids, with its protective groups, is likely part of a larger peptide or protein synthesis process, where the protecting groups are temporarily attached to facilitate the stepwise assembly of the peptide chain.

Check Digit Verification of cas no

The CAS Registry Mumber 79432-38-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,4,3 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 79432-38:
(7*7)+(6*9)+(5*4)+(4*3)+(3*2)+(2*3)+(1*8)=155
155 % 10 = 5
So 79432-38-5 is a valid CAS Registry Number.

Synthesis of Human Growth Hormone-(27-44)-octadecapeptide and some Smaller Fragment Peptides

Chillemi, Francesco

, p. 1913 - 1917 (2007/10/02)

Synthesis in solution of human growth hormone-(27-44)-octadecapeptide and a series of smaller fragments was carried out by a stepwise procedure, starting at the carboxy-terminus and utilizing active esters in the acylation reactions.
