1. Five Sense Biochemistry
Love thy Lipids

2. Lipid Chemistry
Main Elements of Lipids: Carbon hydrogen & oxygen The ratio of hydrogen to carbon is greater than 2:1

3. Lipid Chemistry Lipids are non-polar, hydrophobic molecules
How do lipids behave in the presence of polar molecules such as water?
Lipids include fats, phospholipids, waxes & steroids

4. Function of Fats Energy storage
Fats contain 9 calories/gram whereas carbohydrates contain 4 calories/gram

5. Fats
Fats are composed of glycerol & three fatty acids (tri-glyceride)

6. Saturated Fat
Study the pattern of carbon & hydrogen bonding—why do you think this is a saturated fat?

7. Unsaturated Fat
Study the pattern of carbon & hydrogen bonding—why do you think this is a unsaturated fat?

8. Trans Fats
What makes trans fats different than other unsaturated fats?

9. Phospholipids
Similar to a fat, but contains only two fatty acids and a phosphate group.
Polar heads & non-polar tails
Where are phospholipids found in cells?

10. Steroids (Sterols) Lipids with four fused rings & no fatty acids
Cholesterol is found in cell membranes & plays a role in hormone synthesis
