Review
  • Water is __________________
  • Attractive force between particles of the same kind. ____________________
  • Attractive force between unlike substances. _______________________
  • In a mixture of water and cool-aid which would be the solute and which would be the solvent?
organic vs inorganic
Organic vs. Inorganic
  • Organic Chemistry = carbon chemistry
  • Macromolecules are carbon based
carbohydrates
Carbohydrates
  • Chemical composition: carbon, hydrogen, and oxygen in a 1:2:1 ratio
  • C6H12O6
  • Is C24H48O24 a carbohydrate?
many monosaccharides polysaccharide
Many Monosaccharides= polysaccharide
  • Starch is a polysaccharide and plants store it as starch
carbohydrates function in living things
Carbohydrates function in living things
  • Main source of energy in all living things
nucleic acids
Nucleic Acids
  • Contains the 5 elements- Carbon, nitrogen, phosphorus, hydrogen, and oxygen
  • The monomers or building blocks of Nucleic Acids are nucleotides
slide12

Function in Living Things

- Stores hereditary information

  • Examples: DNA and RNA

Ticket out the Door
  • What is the chemical composition of carbohydrates and what is the ratio?
  • Give an example of a monosaccharide, disaccharide, and polysaccharide
slide14

Draw a picture of the monomer for nucleic acids.

  • What is the monomer for carbohydrates?
  • What 3 elements compose carbohydrates?
  • What are the two types of nucleic acids?
  • Tell me something you already know about lipids.
slide15

Building Blocks:

    • Lipids are made of fatty acids and glycerol.
  • Examples:
    • Phospholipids
    • Waxes
    • Triglycerides
      • Saturated
      • Unsaturated
    • Steroids
      • Hormones
      • Cholesterol
why are lipids important
Why are lipids important?

Primary function is to store energy!

  • Waterproof covering (surfaces of leaves)
  • Protection (earwax)
proteins
Proteins
  • Chemical Composition
  • Carbon, hydrogen, oxygen and nitrogen
  • Building Blocks
  • Amino acids linked together by peptide bonds
proteins1
Proteins
  • R-group in amino acids determine the structure of the protein.
  • 1st- # of a.a. and their order
  • 2nd- 3-D shape
  • 3rd- Globular
  • 4th- combine with other proteins
why proteins are important
Why proteins are important
  • Function in Living Things: Skin and muscles are made largely of proteins
  • Enzymes are proteins.
  • Structural support of cells
  • Cell communication
  • Cell growth
