Question

At ph below the isoelectric point an amino acid exists as

Answer 1

4.6 Isoelectric Point Precipitation. The isoelectric point (pI) is the pH of a solution at which the net charge of a protein becomes zero. At solution pH that is above the pI, the surface of the protein is predominantly negatively charged, and therefore like-charged molecules will exhibit repulsive forces.

$<u>$

4.6 Isoelectric point Precipitation. .

The isoelectric point(pl) is the pH of a solution at which the net charge of a protein becomes zero . At solution pH that is above the pl , the surface of the protein is predominantly negativiely charged, and therefore like charged molecules will exhibit repulsive forces..
