A calculation method of acid dissociation constant, including: calculating the acid dissociation constant using function that uses index value determined based on electron density between two atoms in calculation target molecule and coefficient value determined based on types of two elements of set of the two atoms, wherein when the calculation target molecule includes at least one amino group and dissociation of hydrogen atom from one amino group in the at least one amino group is calculated, the function further uses second electron density of nitrogen atom in the one amino group not related to bond between the nitrogen atom and another atom, bond distance between the nitrogen atom and the hydrogen atom, and molecular orbital energy of the calculation target molecule, wherein the calculation method is method for calculating acid dissociation constant in dissociation of the hydrogen atom from the calculation target molecule using computer.
一种酸解离常数的计算方法,包括利用根据计算目标分子中两个原子间的电子密度确定的指数值和根据两个原子集合的两个元素的类型确定的系数值的函数计算酸解离常数,其中,当计算目标分子包括至少一个氨基且计算至少一个氨基中的氢原子从一个氨基中解离时、该函数进一步使用一个氨基中的氮原子的与氮原子和另一个原子之间的键无关的第二电子密度、氮原子和氢原子之间的键距以及计算目标分子的分子轨道能,其中计算方法是使用计算机计算氢原子从计算目标分子中解离时的酸解离常数的方法。
