  7. the backbones of DNA.

    The 4 DNA gene constructors:
    TCAG- which and which can only be together
    • double helix
    • TA and CG
  8. Nucleic acids-
    1. building blocks of the nucleic acids are ________.
    2. Nucleic acids store and transmit __________.
    3. Are ____________.
    • nucleotides
    • genetic information
    • macromolecules
  9. What elements do Lipids contain
    • Carbon, Hydrogen, Oxygen
    • (CHO) NOT in 1:2:1 ratio
  10. 2 building blocks of lipids
    locate them
    • Fatty acids and glycerol
  11. What are lipids?
    fats (cant dissolve in water)

  12. If the lipid has a single carbon bond, then the lipid is _____________.
    an example would be
    • saturated fat
    • butter
  13. If the lipid has a double carbon bond, then the lipid is _____________.
    an example would be ...
    • unsaturated
    • vegetable oil
  14. What is a phospholipid?
    When replacing one of the fatty acid molecules with a phosphate molecule
  15. what are lipids used for?
    • cushion organs
    • form waterproof coverings (in plants)
    • store energy
  16. What are carbs made of?
    (CHO)Carbon, Hydrogen and Oxygen in a 1:2:1 ratio
  17. examples of carbs (optional:and short definition)
    • sugars- stores energy
    •  starches- plants store glucose in for of starch
    •  cellulose- a bunch of glucose molecule bonds together
  18. what are carbs used for?
    structural support and quick energy
  19. What are the 3 groups Carbs are classified in and what do they mean?
    • Monosaccharaides- contain 1 molecule of sugar
    • (mono- one
    • saccharides- sugar)
    • Disaccharides- 2 sugar molecules put together

    Polysaccharides- many sugar molecules put together
  20. Difference between Polar and Nonpolar
    • Polar ( LOVES Water)
    • nonpolar (Avoids water)
  21. long chains of amino acids are called -
    polypeptides
  22. In amino acids, the "R" group is just a filler. What does that space provide?
    Determination of the amino acid's function
  23. Enzymes regulating chemical process
    proteins
  24. source of all energy
    carbs
  25. examples of monosaccharaides
    glucose, fructose, and galactose

    (mono- in one- and if a monster is one, then he's single. and why is he single. Because he's GGF. Gross, Green, Fat. (Glucose, Fructose, and Galactose)
  26. examples of Polysaccharides
    starch, cellulose, glycogen
  27. what is sucrose?
    • disaccharides-
    • glucose and fructose
  28. glucose and fructose are similar but what's different about them? what do they share in common?
    • the structure.
    • Glucose has one Ch2OH
    • fructose has 2 of that in the molecule

    both monosaccharaides
  29. what is cellulose?
    polysaccharide- a bunch of glucose molecules
  30. in what form do plants store energy?
    humans?
    • plants= starch
    • humans= glycogen
  31. CHON+R group?
    proteins
  32. what synthesizes proteins?
    amino acids
  33. What is sulfur found in?
    proteins
  34. Glucose Polymers:
    1.
    2.
    3.
    • 1. Starch
    • 2. Glycogen
    • 3. Cellulose
    • (way to remember- poly means many and on Christmas you get many gifts. Santa (starch) brings Goodies/Gifts (glycogen) and eats our Cookies (cellulose)--Santa, Goodies, Cookies.)))))))))
  35. Example of Disaccharides
