  • Slide 1
  • Carbon and Organic Chemistry Carbon is a versatile atom. Carbon forms large, complex, and diverse molecules necessary for lifes functions. Organic compounds are carbon-based molecules. Structural formula Ball-and-stick model Space-filling model
  • Slide 2
  • Variations in Carbon skeletons Carbon skeletons vary in length Carbon skeletons may be unbranched or branched Carbon skeletons may have double bonds, which can vary in location Carbon skeletons may be arranged in rings Carbon and Organic Chemistry
  • Slide 3
  • Larger hydrocarbons form fuels for engines. Hydrocarbons of fat molecules fuel our bodies. Hydrocarbons
  • Slide 4
  • *structural isomers *geometric isomers *enantiomers Example of enantiomers: Chemical Components of Cells
  • Slide 5
  • The unique properties of an organic compound depend not only on its carbon skeleton but also on the atoms attached to the skeleton These atoms are called functional groups Some common functional groups include: Hydroxyl groupCarbonyl groupAmino groupCarboxyl group Found in alcohols and sugars Found in sugars Found in amino acids and urea in urine (from protein breakdown) Found in amino acids, fatty acids, and some vitamins Carbon and Organic Chemistry
  • Slide 6
  • *most macromolecules are polymers polymer monomer The making and breaking of polymers: Dehydration reaction:Hydrolysis: Macromolecules
  • Slide 7
  • Proteins Proteins perform most of the tasks the body needs to function They are the most elaborate of lifes molecules MAJOR TYPES OF PROTEINS Structural ProteinsStorage Proteins Contractile ProteinsTransport ProteinsEnzymes
  • Slide 8
  • Carboxyl group Amino group Side group Side group Amino acid Dehydration synthesis Side group Side group Peptide bond Cells link amino acids together by dehydration synthesis Proteins as Polymers The resulting bond between them is called a peptide bond
  • Slide 9
  • Amino Acids
  • Slide 10
  • Primary structure The specific sequence of amino acids in a protein 1 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 95 100 105 110 115 120 125 129 Amino acid The arrangement of amino acids makes each protein different Protein Structure
  • Slide 11
  • A slight change in the primary structure of a protein affects its ability to function The substitution of one amino acid for another in hemoglobin causes sickle-cell disease (a) Normal red blood cellNormal hemoglobin 1 2 3 4 5 6 7... 146 (b) Sickled red blood cellSickle-cell hemoglobin 2 3 1 45 6 7... 146 Protein Structure
  • Slide 12
  • Tertiary structure Secondary structure Macromolecules
