All those groups whose pKa are higher than 7.3 are in protonated state and other are in deprotonated state.
Draw a formula for Ala-Ser-Gly (A-S-G) in its predominant ionic form at pH 7.3. You may assume for the purposes of this...
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). 4. The figure...

hehe instructions: You may work on this individually or in groups. Remember you will each be responsible for knowing the material individually on exam. Please write answers on separate sheet where appropriate. This will be turned at end of class Thursday Oct. 31. credit will be based on combination of participation and attendance. You may pick up your copy of answers outside my office Friday morning and/or view key after class on Blackboard. These are good study questions for your...

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...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
