2. Bio-Molecules: Chemical compounds containing Carbon

3. Bio-Molecules Carbohydrates (sugars) Proteins Lipids(fats) Nucleic Acids (DNA & RNA)

4. Polymerization The construction of larger compounds by joining (bonding) smaller compounds together. Monomers=smaller compounds Polymers=collection of smaller compounds.

5. How Organic Compounds are Formed and Destroyed Dehydration Synthesis Hydrolysis

6. Dehydration Synthesis The combination of two monomers (building blocks) using enzymes and losing water.

7. Hydrolysis The process of breaking down a polymer (large organic molecule) into its sub units using enzymes and water.

8. Carbohydrates (Sugars) Organic compounds with a 2:1 ratio between Hydrogen and Oxygen. (CH 2 O) Monosaccharides (simple sugars) C 6 H 12 O 6 glucose, fructose, galactose, deoxyribose, and ribose sugar Disaccharides (double sugars) C 12 H 22 O 11 sucrose, lactose, maltose. Polysaccharides (complex sugars) (C 6 H 10 O 5 ) n starch, cellulose,and glycogen

9. Carbohydrate Functions Quick energy foods (glucose, sucrose, and fructose.) Used by cells to store and release energy. Storage=polysaccharides (starch, glycogen) Structure (cellulose)

10. Lipids A group of compounds that contain very little oxygen and are insoluble in water. Examples: Fats, Steroids, Cholesterol, and Wax. They are found surrounding internal organs, in each cell membrane, and clogging arteries and veins.

11. Main Types of Fats Saturated: No double bonds between the carbons Solid at room temperature Found mostly in animals. Unsaturated: Double bonds between some of the carbons Liquid at room temperature Found mostly in plants

12. Lipid Functions High Energy food, more for long term energy. More energy than carbs! Protects vital organs Insulates the body Stores food for later use

13. Protein Proteins are organic compounds made up of smaller units called amino acids. Approximately 20 known amino acids. Each amino acid contains an NH 2 or amino group and a CO 2 H or carboxyl group Di/Poly Peptide Bonds

14. Protein Functions Movement: Makes up muscle tissue Transport: Carries oxygen in organisms (hemoglobin). Immunity: Helps fight off foreign invaders (antibodies). Enzymes: Speed up chemical reactions (amylase) Are catalysts. Not used up. Energy source Cell movement

15. Nucleic Acids These are chemical compounds made up of smaller units called nucleotides. Examples are: DNA (Deoxyribonucleic acid) and RNA (Ribonucleic acid).

16. Nucleic Acid Comparison DNA Double Helix ( twisted ladder) Contains the bases A, T, C, & G Contains the code for the bodies proteins RNA Single strand Contains the bases A, U, C, & G Carries the code for a protein, and transfers amino acids to the ribosomes.
