Estimations of molecular weights from sedimentation equilibrium experiments indicate that the degree of aggregation of egg lecithin in benzene solutions increases with increasing addition of water. The molecular weight rises monotopically from about 14,000 in the anhydrous state to about 57,000 at a water/lecithin ratio of 0.31. Sedimentation coefficients were shown to behave in the same manner. Frictional coefficients obtained from the combined results fail to indicate definite differences in asymmetry; however, they seem to indicate that the aggregates in all stages are compact in shape.
通过沉降平衡实验对分子量的估算表明，在苯溶液中，随着水添加量的增加，卵磷脂的聚集程度增大。分子量从无水状态下的约14,000单调上升至水与卵磷脂比例为0.31时的约57,000。沉降系数也表现出相同的行为方式。综合结果得到的摩擦系数未能表明不对称性存在明确差异；然而，它们似乎表明各个阶段的聚集体形状紧密。
