2. WHAT ARE WE MADE OF? ORGANIC COMPOUNDS

3. ORGANIC COMPOUNDS (polymers) CONTAIN the elements CARBON AND HYDROGEN (along with others) BASIC BUILDING BLOCKS OF ORGANISMS

4. Polymers Made of chains of smaller compounds (monomers) Monomers are put together in a process called dehydration synthesis D.S means water is removed

5. Breakdown of polymers When you eat, you break down or digest polymers This break down process is called hydrolysis because water is added to make it happen

6. PROTEIN BASIC BUILDING BLOCK CONSTRUCTED OF CHAINS OF AMINO ACIDS NH2—CCC—COOH Amino carboxyl Can be used for energy Examples: insulin, keratin, collagen

7. CARBOHYDRATE Used mainly for energy Chains of monosaccharides Glucose best known mono- Examples starch, sugar, lactose

8. FAT Used mainly for energy although in packets used for insulation and protection in the body

9. Fat continued Made of chains of fatty acid and glycerol Saturated fat=animal fat Unsaturated=plant oils (liquid at room temp.) Examples: see above

10. Nucleic acid Used for genetic code Made of chains of nucleotides Examples DNA, RNA
