WebOct 30, 2024 · A protein has its lowest solubility in water at its isoelectric point and thus more easily can go into the organic phenol phase within this pH range.Thus a pH between 6.8 to 7.2 is enough for... WebOn the other hand, the addition of phenol changes the solubility of proteins by forcing the hydrophobic non-polar residues (which usually hides on the inside of the proteins and away from the solvent) to interact with the solvent. Hence, the proteins are made more soluble in phenol than in water.
