Yes. MMTK can add missing hydrogen atoms to a rather large class of  
molecules, which includes lipids. However, you need to have a  
database file for the fully hydrogenated lipid. Since the default  
database doesn't have any lipids at all, you will have to write that  
file yourself. Once you have done that, you construct a lipid  
molecule with just the positions of the non-hydrogen atoms and then call
