How Compounds Are Built And Broken Down Dehydration Synthesis and Hydrolysis

Chemical Reactions are represented by chemical equations Chemical Reactions are represented by chemical equations. They are written in the following form: Reactants Products (starting material) (newly formed substances) ex: NaCl Na+ + Cl- Yields H2O

Types of Chemical Reactions: Building molecules Dehydration Synthesis Breaking Down molecules Hydrolysis + +

Dehydration Synthesis an organic compound (polymer) is made from smaller molecules (monomers) by removing water Monomer Monomer Polymer dehydration = removing water synthesis = making a large molecule

Dehydration Synthesis dehydration = removing water synthesis = to build synthesis of polymer

Hydrolysis an organic compound (polymer) is broken down into smaller molecules (monomers) by the addition of water Polymer Monomer Monomer water hydro = addition of water lysis = to break down

hydro = water lysis = to break down Hydrolysis hydro = water lysis = to break down

Dehydration Hydrolysis Synthesis Removal of Water Addition of Water Dehydration Hydrolysis Synthesis (To break down) (To make)

Dehydration Synthesis or Hydrolysis? What type of biomolecule? 1. 2. 3. Dehy. Synth. + Carb. Dehy. Synth. Protein Hydro. Protein

4. 5. 6. Hydro. Protein Dehy. Synth. Carb. Dehy. Synth. + Lipid + + +

7. 8. 9. Hydro. Protein Dehy. Synth. Protein + + + Hydro. Protein

Joining monomers to form polymers is done through a chemical reaction known as Dehydration Synthesis. monomer + monomer + monomer + monomer + monomer + monomer polymer + 5H2O

Breaking down polymers into their individual monomers is done through a chemical reaction known as Hydrolysis. polymer + 5H2O monomer + monomer + monomer + monomer + monomer + monomer
