Spectroanalytical Methods

Spectroanalytical methods measure the wavelength and intensity of radiations that are either emitted or absorbed by a molecular or atomic species. These methods are useful for evaluating the electronic or atomic arrangement of the molecules of a given analyte.

Question

What are the net charges of the following five-amino-acids peptides at pH 14.0 RRKKQ? (please provide detailed step-by-step solution)

1. Draw detailed structures of the 5-amino-acids peptides

2. Identify pKa values of all ionizable functional groups

Definition Definition Group of atoms that shape the chemical characteristics of a molecule. The behavior of a functional group is uniform in undergoing comparable chemical reactions, regardless of the other constituents of the molecule. Functional groups aid in the classification and anticipation of reactivity of organic molecules.

the pKa values for phenylalanine are 1.83 (carboxyl group) and 9.13 (amino group). Use the Henderson-hasselbach equation to determine the ratio of the acidic and basic forms of each of the ionizing groups of phenylalanine at neutral pH. Based on this, draw the predominant structure of phenylalanine at neutral pH.
Glycine is a diprotic acid, which can potentially undergo two dissociation reactions, one for the a-amino group (-NH3), and the other for the carboxyl (-COOH) group. Therefore, it has two pKą values. The carboxyl group has a pK₁ of 2.34 and the a-amino group has a pK₂ of 9.60. Glycine can exist in fully deprotonated (NH₂-CH₂-COO-), fully protonated (NH3-CH₂-COOH), or zwitterionic form (NH3-CH₂-COO-). Match the pH values with the corresponding form of glycine that would be present in the highest concentration in a solution of th pH. fully deprotonated form NH,−CH,−COO- pH 11.9 pH 6.0 pH 8.0 fully protonated form NH3-CH₂-COOH pH 1.0 Answer Bank pH 7.0 zwitterionic form NH3-CH₂-COO-

There are 20 common, naturally occurring amino acids from which all proteins are derived (as will be discussed in Chapter 25), although many other less common amino acids have been isolated from natural sources. Valine is one of the 20 common amino acids, and it was used as a starting material in the laboratory synthesis of an uncommon amino acid (Tetrahedron 1997, 53, 1151-1156). During one of the steps in the synthesis, compound 1 was treated with HBr under conditions that favor radical addition, giving stereoisomers 2 and 3.
