Abstract
Procedures for the determination of equilibrium constants of linear and helical associations based on molecular weight data have been derived. Theoretical construction of curves for M(1)/M(wapp) vs. C reveals two clearly identifiable patterns for linear and helical association. The change in molecular conformation between linear and helical association is evidenced by a recurring pattern of irregular curves which obviously differ from those of an indefinite stacking model.
摘要
基于分子量数据测定线性和螺旋缔合平衡常数的程序已经推导出来。绘制M(1)/M(wapp)对C的曲线的理论构建揭示了线性和螺旋缔合两种明显可识别的模式。线性和螺旋缔合之间分子构象的变化由不规则曲线的重复模式证明，这些曲线明显不同于不确定堆积模型的曲线。
