Draw an approximation for the titration curve of glutamic acid which is the non-ionized or protonated form of glutamate. Make sure to label the axis. Clearly label each pKa on the graph (Hint: it may help you to connect the pK to the x and y axis, but not required). What is the Isoelectric point? Define the term isoelectric point, calculate and label the point on the graph. Draw the major species of glutamic acid with appropriate formal charges at...

A. What is the Isoelectric point pI of the peptide Gly-Glu-Ala-Lys-Val ? B. A purified protein is in a Hepes buffer at pH 7 with 300 mM NaCl. A sample (2mL) of the protein solution is placed in a tube made of dialysis membrane and dialyzed against 1 L of the same Hepes buffer with no NaCl. Small molecules and ions (such as Na+, Cl-, and Hepes) can diffuse across the dialysis membrane, but the protein cannot. 1. Once the...
