section 4,chapter 2

  1. 1. Section 4, Chapter 2 Organic Molecules
  2. 2. Organic Molecules Molecules that contain carbon Organic Synthesis Small molecules (monomers) join together to form larger molecules (polymers) Monomer portion of a polymer
  3. 3. Covalent Bonds formed by Carbon C 12.01 6 Atomic Number of Carbon = 6 2 electrons in 1st shell 4 electrons in 2nd shell Note there are 4 empty spaces in the 2nd shell available for covalent bonds.
  4. 4. Examples of covalent bonds formed by carbon Carbon can form 4 covalent bonds Carbon can also form double or even triple bonds Carbon to Carbon bonds can form long chains hydrocarbon
  5. 5. Polymers and Monomers Large organic molecules, called polymers consist of repeating subunits, called monomers. Example: Starch is a polysaccharide composed of many glucose molecules (monosaccharides) joined together.
  6. 6. major organic macromolecules of the cell Monomer Polymer Monosaccharide (simple sugars) Disaccharides (double sugars) Polysaccharides (complex carbohydrates) Amino Acids Proteins Fatty Acids + Glycerol Fats* *Not truly a polymer Nucleotides Nucleic Acids
  7. 7. Carbohydrates Simple carbohydrates = sugars Monosaccharides Disaccharides Complex Carbohydrates Also called Polysaccharides Composed of several simple carbohydrates
  8. 8. monosaccharides Twice as many Hydrogen as Oxygen atoms Example: Glucose (C6H12O6)
  9. 9. disaccharides 2 monosaccharides bonded together Examples of disaccharides
  10. 10. polysaccharide Built of simple carbohydrates
  11. 11. examples of polysaccharides Starch – easily digested Cellulose- Plant polysaccharide, indigestible by humans Glycogen – storage form of energy, synthesized by liver Glycogen
  12. 12. Glycerol Molecule OH (in red) represents sites of fatty acid attachments
  13. 13. Unsaturated fat
