Log D is a commonly used parameter to determine the lipophilicity of ionizable compounds. This coefficient measures how the compound will partition between a hydrophobic and a hydrophilic phase at a particular pH. The value of Log D is influenced by the degree of ionization of the compound in the medium of interest. Therefore, it is a pH-dependent parameter and can provide information about the solubility, absorption, and bioavailability of a drug compound in different physiological environments.What is the D molecule's logarithmic value in the negative form?
