A protein with an isoelectric point of 9.1 in a buffer of pH 5.2 will
A) Have a net negative charge
B) Be neutral
C) Have a net positive charge
Please explain, thank you.
Homework Answers
C) Have a net positive charge
At its isoelectric point peptide would have no charge whereas below its isoelectric point peptide would have a positive charge and above its isoelectric point, the peptide would have a negative charge. The pH of the buffer is 5.2 which is lower than the isoelectric point of the peptide so the peptide would have a net positive charge.

Protein molecules in solution can be separated from each other by taking advantage of their net charges. In the electric field between two electrodes, a positively charged particle moves toward the negative electrode and a negatively charged particle moves toward the positive electrode. This movement, known as electrophoresis, varies with the strength of the electric field, the charge of the particle, the size and shape of the particle, and the buffer/polymer gel combination through which the protein is moving. The...

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...
