1. Organic Molecules (Macromolecules ) Building Blocks of Life

2. Organic Molecules  Molecules that have carbon atoms C 6 Carbon 12.011

3. Carbon is a component of all organic molecules  Can share 4 outermost electrons 6 P 6 N e-

4. Carbon Compounds  Can have many carbon atoms  Can from single, double, and triple bonds with other carbon atoms C CC CC C

5. 4 Principle Types of Organic Compounds  Carbohydrates  Fats  Proteins  Nucleic Acids

6. Carbohydrates  Made of C, H, and O  Building block: simple sugars (monosaccharides-single sugar)

7. Disaccarhides  Two monosaccharides linked together by a condensation reaction

8. Polysaccharides Largest carbohydrate molecule Composed of many monosaccharide units Common examples: Starch, Glycogen, Cellulose

9. Lipids (Fats & Oils) :

10. Lipids  Made of C, H, and O (but less O than a carb)  Building block: 1 glycerol backbone + 3 fatty acids

11. Lipids Saturated: has single covalent bonds between each carbon Unsaturated: has double covalent bonds between carbons

12. Proteins  Made of C, H, O, S, N  Building block: amino acids

13. Nucleic Acids  Made of C, H, O, N, P  Building block: nucleotides

14. 5 types of nitrogen bases

15. Nucleic Acids  DNA-2 chains  RNA-1 chain  Stores genetic info—unique order of nucleotides for each living organism  Nucleotide order determines amino acid order
