Q. The properties of the R groups of amino acids determine the behavior and structure of proteins. Compare the hexapeptide: Leu-Arg-Thr-Phe-Pro-Glu with the five peptides given below. Which would have the most analogous properties to the one above? A) Val-Lys-Met-Tyr-Pro-Asp B) Asp-Lys-Ser-His-Pro-Asp C) Ile-Lys-Cys-Trp-Pro-Asp D) Ala-Leu-Tyr-Leu-Pro-Asp E) Val-His-Cys-Trp-Gly-Gln
