Explain the Titration profile of Lysine

Devise a solution-phase synthesis of Ala-Leu-Val-Phe-Met, starting from the requisite Boc-protected amino acid

Draw the structure of Arg - Lys - Ser - Trp at ph 7.4

Draw the structure of Pro-Leu-Glu at physiological pH (7.4).

Lactose exists in two anomeric forms, but no anomeric forms ofsucrose have been reported. Why?

draw the structure of the tripeptife Pro-Ser-Cys as it would appear at physiological PH with its C-terminal amino acid residue protected as its methyl ester

Draw the structure of the PTH derivative you would obtain by Edman degredation of the peptide: ALPF.

Draw the tetrapeptide Met-Ile-Lys-Glu at a ph of 7?

Identify the 20 amino acids and their corresponding three-letter and one-letter abbreviations

a. Suppose that you have the peptide Ala-Gly-Tyr-His-Leu and you treat it with FDNB and then 6M HCl. Draw the structures of all the products that you will have in solution (assume all reactions to go to completion).
