Chemistry log p
WebpKa = -log[Ka] Acid dissociation constants, or pKa values, are essential for understanding many fundamental reactions in chemistry. These values reveal the deprotonation state of a molecule in a particular solvent. There is great interest in using theoretical methods to calculate the pKa values for many different types of molecules. Calulation ...

WebApr 25, 2024 · Octanol-water partition coefficient: A simple measure of the hydrophobicity of chemicals, originating from pharmacology, is the octanol-water partition coefficient, abbreviated as K ow (and sometimes also called P ow or P oct): this is the ratio of concentrations of a chemical in n-octanol and in water, after establishment of an … WebAbstract. Although log P is now recognized to be a key factor that determines the bioactivity of a molecule, the focus of medicinal chemists on hydrophobicity and log P started with the quantitative structure-activity relationships (QSAR) publications of Hansch and Fujita.
