1. Monomer 2. Polymer 3. Carbohydrate 4. Lipid 5. Nucleic acid 6. protein

 Students will explore organic compounds.  Students will compare and contrast the 4 major bio molecules through lecture, note-taking and construction of a foldable.

 Micro- small  Macro- large  Mono- one  Bi- two  Poly - many

Carbon – part of all organic compounds (living things) Unique because – 4 valence electrons lets it bond to other molecules and itself (in single, double or triple bonds) to make large and complex structures

 MACROMOLECULES  made by polymerization-large compounds built by joining smaller ones together.  Smaller units are called monomers.  4 major molecules important to life.  Carbohydrates, lipids, nucleic acids and proteins.

 1:2:1 RATIO  1 Carbon: 2 Hydrogen: 1 Oxygen  Main source of energy for living things  Also has structural purpose for living things. 1. Plant cells have cell walls made of cellulose 2. Animal cells store excess sugars as glycogen

 Primaily Fats  Made of Carbon and Hydrogen.  NOT soluble in water  doesn’t mix with water  Used to store energy  Part of the cell membrane.  Saturated-Solid at room temperature.  No double bonds  Unsaturated-liquid at room temperature. Double bonds between Carbons.

 Composed of Hydrogen, Oxygen, Nitrogen, Carbon and Phosphorus.  Subunits are called nucleotides.  Store and transmit hereditary information.  Examples: DNA, RNA

 Composed of Nitrogen, Carbon, Hydrogen, and Oxygen.  Monomers are called amino acids  Control rate of reactions  Function in transport and formation of bone and muscle cells.  Folded shape is important in enzyme recognition process.

 Let’s make a foldable of the 4 different biomolecules
