Description:
<jats:p>A macromolecule of protein and chondroitin sulfate (PP-L) inhibits sedimentation of barium-polystyrene sulfonate (BaPSS) and of calcium phosphate at low but not at high values of gravity. Sedimentation of BaPSS removes a large fraction of PP-L from solution, but sedimentation of calcium phosphate does not. The results suggest entanglement among linear polyanionic chains.</jats:p>
