Lipid-like and un-matched % are based on MSCC compound category criteria. Condensed hydrocarbon-like category was defined by the classical van Krevelen diagram criteria. Because four MSCC categories are not shown, row sums do not equal 100%. Refer to text for information about classification approaches.
