STRUCTURE WILL VARY DEPENDING IF PKA IS LARGE OR SMALL,
Draw a formula for Val-Ser-Gly (V-S-G) in its predominant ionic form at pH 7.3. You may assume for the purposes of this question that the pKa values of the acidic groups of amino acid residues in the peptide are the same as in the amino acid itself. You do not have to consider stereochemistry. You do not have to explicitly draw H atoms. Do not include lone pairs in your...

2. Silk contains the repeating sequence
(Gly-Ser-Gly-Ala-Gly-Ala)n. This sequence is present in beta
strands that interact with each other. Considering just a single
strand within a sheet, the Ser and Ala side chains will be
(on both sides of the sheet in a single repeat) (in first repeat,
on one side; in the next repeat on the other side) (the answer
depends on whether the strands are parallel or antiparallel) (on
the same side of the sheet).

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
