  1. Lipid Review

  2. 1. What are the four examples of lipids?

  3. Saturated • Unsaturated • Sterol • phospholipid

  4. 2. What are the three functions of lipids?

  5. Energy storage • Chemical messengers • Form biological membranes

  6. 3. What are the two components or parts of a lipid?

  7. Glycerol • Fatty acid

  8. 4. What is a fatty acid made from?

  9. Long hydrocarbon chain with a carboxyl group

  10. 5. What is a glycerol made from?

  11. 3 carbons and 3 OH groups

  12. 6. How can you identify a lipid? (What is the ratio of carbon, hydrogen, and oxygen.)

  13. 1carbons for every 2 hydrogen and very few oxygen atoms

  14. 7. What type of bonds are between the carbon atoms in a saturated fat?

  15. All single bonds

  16. 8. At room temperature are saturated fats solids or liquids?

  17. solids

  18. 9. Where do we find saturated fats? (What type of foods?)

  19. Meats and dairy

  20. 10. What do you have to have between carbon atoms to form an unsaturated fat?

  21. At least one double bond

  22. 11. What type of fat forms when more than one double bond is found between the carbon atoms?

  23. polyunsaturated

  24. 12. What happens structurally in an unsaturated fat that causes it to be a liquid at room temperature?

  25. It gets a kink or a bend in the molecule, this prevents them from being packed closely together.

  26. 13. What do sterols do in the body?

  27. Chemical messengers

  28. 14. Write an example of a sterol.

  29. Cholesterol

  30. 15. What do phospholipids form?

  31. Bilayers for membranes

  32. 16. What does hydrophobic mean?

  33. water fearing

  34. 17. What does hydrophilic mean?

  35. Water loving

  36. 18. What type of molecule is shown below?

  37. carbohydrate

  38. 19. What type of molecule is shown below?

  39. Unsaturated fat

  40. 20. What type of molecule is shown below?

  41. Saturated fat
