  1. What is a triacylglycerol?
    • Three fatty acids linked to one glycerol molecule.
  2. MACROMOLECULE!!!!!!
    Giant molecule formed by the joining of smaller molecules usually by a condensation reaction. Polysaccharides, proteins, and nucleic acids are macromolecules.
  3. Nucleic Acid
    A polymer (polynucleotide) consisting of many nucleotide monomers; serves as a blueprint for proteins and, through the actions of proteins, for all cellular activities. The two types are DNA and RNA.
  4. Carbohydrate
    A sugar. Plain and simple.
  5. Glycogen
    An extensively branched glucose storage polysaccharide found in the liver and muscle of animals; the animal equivalent of starch.
  6. Monosaccharide
    Known as a simple sugar, generally the formula is some multiple of CH2O
  7. Which functional group can be considered either an aldehyde or a ketone?
    Carbonyl Group
  8. Starch is a...

    A)Monosaccharide
    B)Disaccharide
    C)Polysaccharide
    C) Polysaccharide
  9. Glucose is a....

    A) Monosaccharide
    B)Disaccharide
    C)Polysaccharide
    A)Monosaccharide
  10. Sucrose is a...

    A) Monosaccharide
    B)Disaccharide
    C)Polysaccharide
    B)Disaccharide
  11. Which two polysaccharides are used for energy storage?
    Glycogen and Starch
  12. Which two polysaccharides are used for structure?
    Cellulose and Chitin
  13. Which polysaccharide used for energy storage is released s l o w l y?
    Starch, because it is in linear form and it isn't branched. Remember, Starch = Slow.
  14. Which polysaccharide used for energy storage is released quickly?
    Glycogen, because it is branched, making it easier to break off from other molecules in the chain.
  15. What type of bond links fatty acid chains to glycerol molecule?
    Ester Linkage. Think, Ester sounds like a fat chick name and Ester Linkages make up fats.
  16. Name the three parts of a phospholipid.
  17. Cholesterol and sex hormones are an example of what? What is the definition?
    Steroid: A type of lipid characterized by a carbon skeleton consisting of four rings with various functional groups attached.
  18. What four components make up an amino acid?
    • Carboxyl Group: Gives acidic properties and name
    • Amino Group: Gives NH2 and amino name
    • Central Carbon: AKA asymmetrical carbon
    • "R" Group: AKA functional group
  19. A peptide bond is a covalent bond between the [blank] group of one amino acid to the [blank] group of another.
    Amine, Carboxyl C-N
  20. Which protein structures are altered when a protein is denatured?

    A) Primary
    B) Secondary
    C) Tertiary
    D) Quaternary
    E) Primary and Secondary
    F) Secondary and Tertiary
    G) All levels are altered
    F) Secondary and Tertiary
  21. Nucleic acids function generally is to.......
    Transfer and store information
  22. The three parts that make up a nucleotide are:
  23. A sugar-phosphate bond is called a....
    Phosphodiester bond!
  24. What type of bond joins the two strands of DNA?
    A hydrogen bond
