Hofmeister lyotropic series
Nettet22. sep. 2024 · The Hofmeister or lyotropic series describes the salting-out effects of ions on proteins . The hydrophobicity of the anions studied was in the following order: ClO 4 − > Cl − > CH 2 COO − > HPO 4 2 − /H 2 PO 4 − , showing that the partitioning of the salt to the relatively more-hydrophobic top phase was enhanced with increases in the …
