Biological Molecules

• Long hydrocarbon tails of fatty acids


  Contain large amounts of chemical energy, released when fatty acids are broken down
• Triglycerides are insoluble


  Energy storage molecules, do not not affect water potential inside the cell.
• Chromatography is a technique that can be used to separate a mixture into its individual components. 


  Relies on differences in solubility of solutes.
• Components in mixture separate as mobile phase travels over the stationary phase.
