Abstract
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.
摘要
一种由蛋白质和硫酸软骨素组成的大分子（PP-L）在低重力值下可抑制聚苯乙烯磺酸钡（BaPSS）和磷酸钙的沉降，但在高重力值下则无此作用。BaPSS的沉降会使溶液中的大部分PP-L去除，但磷酸钙的沉降则不会。结果表明线性聚阴离子链之间存在缠结。
