Y Do you predict that this salt bridge will become stronger, become weaker, or be unaffected as pH increases from pH-7.2 to pH=7.97 The salt bridge will become stronger. The salt bridge will become weaker. The salt bridge will be unaffected. Previous Answers Correct At pH=7.2 the glutamic acid (Glu) side chain will carry a charge of -1 (at 3 pH units above the pK, for Glu, the side chain will be almost fully ionized whereas the histidine (His) side chain will carry a charge of < 0.5 (at pH pK, the charge on His would be +0.5; since pH 7.2 is above its pK, it will carry less (+) charge as it becomes more deprotonated). As the pH increase to 7.9, the charge on Glu will remain-1 and the charge on His will decrease; thus, this salt bridge is predicted to become weaker as pH is raised from 72 to 7.9. Part B Justify your answer with calculations of partial charges on these amino acid side chains at pH 7.2. (Hint: Consider lessons from Coulomb's law, and the Henderson Hasselbalch equation)…

Time to purify biochemisfunase! To do this, you’ll need to make MORE buffers. One of the buffers that you need to make requires 150 mM Tris (pH 8), 250 mM sodium chloride (NaCl) and 2 mM dithiothreitol (DTT, a reducing agent that prevents the formation of disulfide bonds in proteins). Your jolly postdoc friend wants you first to make 500 ml of a1.0M Tris stock solution before making the buffer. Describe how you would make this stock solution, and show all calculations.
