The polar solvent systems, such as BAW or sec -butanol-water, which are useful for peptides, proteins and other high MW entities, were not satisfactorily retained in the multilayer coil in the type J planetary centrifuges. Thirty-nine dyes were subjected to thin layer chromatography to evaluate eight different solvent systems. Mixtures of n -butanol, glacial acetic acid, and water were studied with this concept in mind. When an 80% phenol in water solvent is used, lysine has an Rr value of 0.71. An equilibrium between two acids will result in the equilibrium favoring formation of the weaker acid (lower pKa value).Q: Predict which functional groups in the amino acids aspartic acid and phenylalanine are expected to be Butanol: Acetic acid: Water (12:3:5) is a suitable solvent for separating amino acids.
