The product(s) of each of the given reactions are to be determined. Concept Introduction: 1 -fluoro-2,4-dinitrobenzene is used to protect the anime group of an amino acid. Hydrolysis of a peptide with a 1 -fluoro-2,4-dinitrobenzene protected N terminus results in hydrolysis of amide bonds in the peptide. Treatment of a peptide with phenyl isothiocyanate protects the N terminus of the chain. Subsequent treatment with a strong acid in anhydrous conditions cleaves only the amide bond between the protected amino acid residue and the rest of the peptide chain. Benzyloxycarbonyl chloride is used to protect the amine group of an amino acid. N,N'-dicyclohexylcarbodiimide is used as a dehydrating agent in peptide and ester formation reactions. Hydrogenolysis with hydrogen over palladium is used for deprotection of N terminus.

Draw the structure of the tetrapeptide Asp-Arg-Val-Tyr. Please show the appropriate stereochemistry of the natural amino acids in the resulting peptide. Please draw all ionizable groups in their neutral form.

Somatostatin is a tetradecapeptide of the hypothalamus that inhibits the release of pituitary growth hormone. Its amino acid sequence has been determined by a combination of Edman degradations and enzymic hydrolysis experiments. On the basis of the following data, deduce the primary structure of somatostatin: 1. Edman degradation gave PTH-Ala. 2. Selective hydrolysis gave peptides having the following indicated sequences: Phe-Trp Thr-Ser-Cys Lys-Thr-Phe Thr-Phe-Thr-Ser-Cys Asn-Phe-Phe-Trp-Lys Ala-Gly-Cys-Lys-Asn-Phe 3. Somatostatin has a disulfide bridge.

Using the information below, determine the amino acid sequence of the peptide, and explain how your structure is consistent with each piece of information. Complete hydrolysis by 6 M HCl at 110°C followed by amino acid analysis indicated the presence of Gly, Leu, Phe, and Tyr in a 2:1:1:1 molar ratio. Treatment of the peptide with1-fluoro-2,4-dinitrobenzene followed by complete hydrolysis and chromatography indicated the presence of the 2,4-dinitrophenyl derivative of tyrosine. No free tyrosine could be found. Complete digestion of he peptide with pepsin (which cleaves on the amino side of aromatic residues) followed by chromatography yielded a dipeptide containing Phe and Leu and a tripeptide containing Tyr and Gly in a 1:2 ratio.
