Reversing Hydrolysis
When water is being taken out of a Polymer:  It's called Dehydration Synthesis or Condensation
Condensation
 Reaction- When an OH and an H are stripped off of 2 Monomers to form a Dimer (Polymer). After this process you get H20 as a byproduct.

2. Lactose = Glucose - Galactose
       Water is then used to break up the bond between the two sugars, which then gives you another Glucose as the product of the reaction.                                         
                                                        Glucose- Galactose -------> Glucose
                                                                    ^
                                                                  H20
C. Polysaccharides - Long chains of Glucose
                   1. Starch - the way that plants store glucose before the winter. (almost all plants use starch to store glucose except for Annuals)  ( Starch can be easily converted to glycogen my our body)
                   2.  Glycogen - The way that animals store glucose.  It is stored in our muscles and  Liver. "Muscle Fuel"  Midterm Energy
                   3. Cellulose - Forms the cell walls of plants- this is what gives then their rigidity---WOOD

II  Lipids - Generally serve as long-term fuel storage compounds.  They are composed of Carbon, Hydrogen, and Oxygen (but very few Oxygen atoms)
