Package chemaxon.marvin.calculations

Interface HlbPlugin

@PublicApi public interface HlbPlugin
Calculates hydrophilic-lipophilic balance (HLB) of a molecule. The HLB is a measure of the degree to which molecule hydrophilic or lipophilic, determined by calculating values for the different regions of the molecule, as described by Griffin. Other methods have been suggested, notably in by Davies.

API usage example: 

 // construct the plugin class
 HlbPlugin plugin = HlbPlugin.Builder.createNew();
 Molecule mol = ...

 // set the input molecule and run calculation
 plugin.setMolecule(mol);
 plugin.run();

 // get HLB values
 plugin.getDaviesHlbValue();
 plugin.getGriffinHlbValue();

    • setRHLB

      void setRHLB(boolean r)
      User can inquire the so called rHLB value. The rHLB value is not calculated as default.
      Parameters:
      r - specify wheter the rHLB value is calculated or not. if r=true than the rHLB value is calculated.
