Lipophilicity represents the affinity of a molecule or moiety for a lipophilicenvironment. It is commonly measured by its distribution behavior in abiphasic system, either liquid-liquid (e.g.,partition coefficient in octanol/water) or by chromatographic methods [1]. Knowledge of lipophilicity isused in a variety of methods that may predict absorption and other transportproperties of drug molecules in the human body. 解離常數(shù)/油水分配系數(shù)(pKa/LogP)測(cè)定儀
