  1. Lipids

  2. A. Students know most macromolecules (large molecules – proteins, fats, and carbohydrates) in cells are synthesized (made) from a small collection of simple parts.

  3. Important in Energy Storage Students know most macromolecules in cells are synthesized from a small collection of simple parts.

  4. Fats are lipids made fromglycerol and fatty acids

  5. Lipidsare hydrophobic

  6. Triglycerides glycerolmolecule and 3 fatty acids Non-polar Hydrophobic Students know most macromolecules in cells are synthesized from a small collection of simple parts.

  7. Fatty acids link to glycerol by dehydration synthesis Students know most macromolecules in cells are synthesized from a small collection of simple parts.

  8. saturatedwhen it contains no double bonds between the carbon atoms. Students know most macromolecules in cells are synthesized from a small collection of simple parts.

  9. Saturated Fats • Animals make Saturated Fats • They are Solid at room Temperature

  10. When there is at least one double bond between the carbons a fat is said to be unsaturated. A polyunsaturated fat is considered the healthiest for you.

  11. Unsaturated • Plants • Liquid at room Temperature

  12. Pause for adding to notes • What are the two small parts that make up a macromolecule of a fat? • What is an example of a saturated fat? • What is a difference between a saturated and unsaturated fat?

  13. Phospholipids • Two fatty acids • instead of three • Present in • cellular boundaries Students know most macromolecules in cells are synthesized from a small collection of simple parts.

  14. Make up Cell Boundary Students know most macromolecules in cells are synthesized from a small collection of simple parts.

  15. Pause • Illustrate a Phospholipid • What is a difference between a phospholipid and Triglyceride?

  16. Steroids are lipids composed of fused ring structures Students know most macromolecules in cells are synthesized from a small collection of simple parts.

  17. Androgens, estrogens, progestagens Students know most macromolecules in cells are synthesized from a small collection of simple parts.

  18. Anabolic steroids Students know most macromolecules in cells are synthesized from a small collection of simple parts.

  19. Cholesterol Students know most macromolecules in cells are synthesized from a small collection of simple parts.
