organic compounds
Organic Compounds
  • Organic Compound – a covalently bonded compound that contains carbon
  • Carbons form 4 covalent bonds in organic compounds
types of organic compounds
Types of Organic Compounds
  • Hydrocarbons – a compound that contains only hydrogen and carbon
    • Ex) CH4 (or methane)
  • Alkanes – a compound with only single covalent bonds
    • Ex) CH4 – (or methane)
    • In alkanes, the number of Hydrogens is two more than twice the number of Carbons
types of organic compounds1
Types of Organic Compounds
  • Alkenes – double carbon to carbon bonds
    • Ethene:
  • Alcohols have an –OH group (hydroxyl)
    • Methanol: CH3OH
polymers
Polymers
  • Polymer – a molecule that is a long chain of smaller molecules (monomers)
    • Has repeated subunits
    • Ex) polyethylene is made of many units of ethene
    • Ethene is the monomer that makes up the polymer
polymer
Polymer
  • Can be natural or synthetic
    • Rubber, DNA are natural polymers
    • Plastic is a synthetic polymer
  • Structure determines elasticity
    • If it is made of long chains, it is flexible but not elastic (milk jugs)
    • If it is made of connecting and branching chains, it is stretchy (rubber bands)
biochemical compounds
Biochemical Compounds
  • Compounds essential to life
  • Include carbohydrates, proteins, and DNA
carbohydrates
Carbohydrates
  • Carbohydrates – class of molecules that includes sugars, starches, and fiber
    • Contains hydrogen, carbon, and oxygen
    • Mashed potatoes and candy
proteins
Proteins
  • Proteins – organic compound that is made of one or more chains of amino acids
    • Principal component of all cells (provide structure and function)
    • Hair
  • Amino Acid – a class of simple organic compounds that contain a carboxyl group (-COOH) and an amino group (-NH2)

DNA
  • DNA – polymer that stores information
  • Contains C, H, O, N, P
  • Consists of paired strands that are twisted into a double helix
  • DNA is the information your cells use to make proteins
lab analysis
Lab Analysis
  • What happens when it is stretched or rolled into a ball and bounced?
  • Compare the properties of the glue with the properties of the goo?
  • Does the material have the properties of a polymer?

Answer these about yesterday’s lab on the back of your quizlet.
  • What happens to the goo when it is stretched or rolled into a ball and bounced?
  • Compare the properties of glue and the goo
  • Does the goo have the properties of a polymer? Explain.
