7 Fats vs. Oils

8 Essential Fatty Acids

9 Trans Fats Notice the position of the hydrogen atoms where the double bonds are. Which shape is more like saturated fatty acids?

10 Trans Fats How do we get trans fatty acids? How does this affect the properties of the molecule?

12 Effects of Trans Fats

13 B. Phospholipids

14 Phospholipid Bilayer of Cell Membrane -“like” molecules attract “like” molecules

15 C. Steroids cholesterol Sex Hormones

16 Effects of Testosterone

17 Side Effects of Steroids

18 Cholesterol: The Good, The Bad, The Ugly LDL: low density lipoprotein (bad) HDL: high density lipoprotein (good) Leads to atherosclerosis

Fats (an example of a lipid) Glycerol – Has three –OH groups – Polar molecule Soluble in water Fatty Acids – Long chains of hydrocarbons Insoluble in water.

Lipids. Macromolecule #2: Lipids  Hydrophobic (nonpolar) = insoluble in water  Contain C, H, O (less O than carbs), sometimes P Main types: Triglycerides.
