WebThe phosphorylated proteins were adsorbed by ligand exchange of phosphate for hydroxyl even when an electrostatic repulsive force was present. However, the extent (adsorptive capacity) and strength (adsorptive coefficient) of adsorption was inversely related to the degree of phosphate substitution of the aluminum hydroxide adjuvant. WebLigand 1 contains a resorcin [4]arene 24,25 macrocycle comprised of four phosphate substituted aromatic units. The macrocycle shows some degree of flexibility, as the structure rapidly interconverts between two equivalent boat conformations, but full rotation is prevented through its alkyl feet (Fig. S18–S20, ESI † ).
