NOTES: Unit 1-Organic Molecules NAME 9-24-09 HOUR NOTES: Unit 1-Organic Molecules

(1) What does Organic mean? Organic Food = Fruits & Vegetables which were grown and processed with less than 5% use of pesticides/chemicals Organic Molecule = Contains Carbon This is what we are talking about! ALL Living Things are made of Carbon-Molecules!

(2) Carbon Lots of Bond Openings = Variety of Arrangements & Molecules Carbon has 4 Valence Electrons Carbon wants 8 total Valence Electrons Carbon can share 4 more! 4 more valence electrons 4 available bonds Lots of Bond Openings = Variety of Arrangements & Molecules

(3) Common Biological Elements Carbon (C) Hydrogen (H) Oxygen (O) Nitrogen (N) Phosphorus (P) Sulfur (S) CHONPS!

(4) Types of Organic Molecules Organic Molecule = Biomolecule TYPES: Carbohydrate Lipid Protein Nucleic Acid

(5) Water NOT an Organic Molecule…. BUT…. Cells ~ 70% Water! (Necessary for Life) Unique Properties: High Heat Capacity Polar Neutral Solution for Nutrients Reacts to Form or Break Down Molecules
