  1. *What are fats called when they are combined with proteins?*
    Lipoproteins- which are proteins that carry the lipids around
  2. What are the functions of cholesterol?
    • A. Precursor of steroid hormones
    • B. Precursor of Vitamin D
    • C. Structual of the Cell Membrane
  3. *What kind of food is high in cholesterol?*
    Animal Fats
  4. Two sources of Cholesterol?
    • Animal Fats
    • Your body makes it out of calories
  5. What should be done to reduce a high serum cholesterol level?
    • A. Decrease preformed cholesterol.
    • B. Decrease total calorie intake.
    • C. Increase exercise.
  6. *What does VLDL, HDL, and LDL stand for and what roles do they play?*

    • VLDL: Very Low Density Lipoprotein - carries fats to the tissues and unloads fats and becomes LDL.
    • LDL: Low Density Lipoprotein - Artery clogging. Pieces become stuck along blood vessel walls.
    • HDL: High Density Lipoprotein - Heart helping. Carries stuck pieces back to liver.
  7. *What kind of cholesterol is desiable to have?*
    HDL and excersie increases HDL
  8. *How does the body rid itself of cholesterol?*
    Through bile
  9. *What does the precipitation of cholesterol in the gall bladder cause?*
    Gall stones
  10. What is Atherosclerosis
    Lipid deposits in the arterial walls causes CAD (coronary artery disease associated with increased LDL and decreased HDL)
  11. Which diagnoses are made from cholesterol, triglyceride, and LPE results?
    • LPE- is lipoprotein electrophoresis
    • Result: Familial Hyperlipoproteinemias Type I- V
  12. *What is the meaning of these different cholesterol values? Which one is correlated to coronary artery disease?*
    • Below 200 mg/dL ---desirable
    • 200 - 239 mg/dL ----borderline
    • 240 mg/dL and above ---- High risk statistical correlation to CAD
    • HDL should be greater than 35mg/dL
    • LDL should be less than 130mg/dL
    • Triglycerise shoul be between 30 - 190mg/dL
  13. *What ratio is used to predict the risk of a person getting clogged arteries?*
    • Total Cholesterol
    • HDL

    < 4 or 5 is desirable
