For the given molecules, the electron-dot structure and geometry has to be determined. Concept Introduction: Electron-dot structure of molecule that represent the bonding between atoms of a molecule and the lone pairs of electrons by using dots around the respective atom in that molecule. Molecular geometry can be predicted from the structure by using the valence-shell Electron-pair repulsion (VSEPR) model. Count the number of valence electron pairs (bond pairs and lone pairs). Assume that the valence electron pairs form a structure that allows them to be as far away from each other as possible. If there are only two bond pair electrons, the molecule is linear. If there are three bond pair electrons, the molecule is shaped like a trigonal planar. If there are four bond pair electrons, the molecule is shaped as a regular tetrahedral. Repulsion between lone pair-bond pair of electrons effect the geometry of molecules.

The isoelectric point of eIF4a is 5.02. Students are given a sample of cell lysate containing eIF4A at pH 7.4. They are also provided with two buffers of pH 7.4 to use for ion exchange chromatography. One buffer has a very high salt concentration (1 M), the other has a low salt concentration (0.1 M). Mariela decides to use an anion exchange column, while Ashok chooses a cation exchange column. Who made the better decision? Provide a detailed explanation of why one student will end up with a purer sample of eIF4A. Which buffer will you use while washing away impurities (high or low salt), and which would you use to remove eIF4A from the column? Explain your choice.

Draw dipeptide Arg-Thr at pH 6.0. Circle the six atoms that are restricted in one plane. Calculate its approximate pI assuming pKa for NH3+ is 10.0, pKa for COOH is 3.0, PKR for Arg is 12.0

What volume of 0.1M NaOH (reagent) needs to be added to increase your 7.5 pH (buffer) by 0.5 pH units. The goal is to further purify MOPs (see image). Protonated form = 6.6 x 10.3^-3 mol/L Deprotonated form = 1.32 x 10^-2 mol/L Show calculations.
