Structure Carbon, Hydrogen, and Oxygen Arranged in chains Glycerol & fatty acids are the monomers Water is polar and lipids are nonpolar, therefore they do not mix. Examples: Fats, Oils and Waxes

LIPIDS Saturated: Typically bad fats has maximum number of H bonds Saturated with hydrogen usually solid at room temperature Unsaturated: Typically vegetable oils at least one double bond causes “kinks”/bends = makes close packing much more difficult usually liquid

Glycerol backbone Triglyceride 3 (tri) fatty acid tails

Fats and oils have different types of fatty acids. saturated fatty acids unsaturated fatty acids

Lipid Cut and Paste in Journal Notes to Add: Function: long term energy, components of the cell membrane Next to picture: This is a picture of a saturated fatty acid because they bonds are all straight lines A glycerol with 3 fatty acid chains

Critical Writing On level- How do lipids compare to carbohydrates? How do they different from carbohydrates? Pre-ap- How do lipids compare to carbohydrates? How do they different from carbohydrates? Explain how a triglyceride is formed.
