1. Biological Molecules Polymers & Monomers

2. Hydrogen Bonds

5. Polymer Formation

6. Polymer … is a large molecule formed from repeating subunits of smaller molecules

7. Polymers Monomers Protein Carbohydrate Lipids Nucleic Acid (DNA)

8. Polymers Monomers ProteinAmino Acids Carbohydrates Monosaccharides Lipids Fatty acids, glycerol Nucleic AcidNucleotides

9. DEHYDRATION SYNTHESIS … forms large molecules (polymers) from small molecules. (Dehydration = to remove water)

10. HYDROLYSIS (hydro = water, lysis = to split): is the opposite reaction. Water breaks up a larger molecule. The addition of water leads to the disruption of the bonds linking the unit molecules together. This also requires the action of helping molecules called enzymes. Enzymes that do this are called hydrolytic enzymes.
