6. Concentrated energy molecules
Lipids
Concentrated energy molecules

7. Lipids Examples fats oils waxes hormones sex hormones
testosterone (male)
estrogen (female)

8. Lipids Function: energy storage cell membrane cushions organs
used during low glucose availability
very concentrated
twice the energy as carbohydrates!
cell membrane
cushions organs
insulates body
think whale blubber!

9. Structure of Fat: Monomer isTriglyceride
not a chain (polymer) = just a “big fat molecule”

Most animal fats
solid at room temperature

11. Saturated Fats Limit the amount in your diet
contributes to heart disease
deposits in arteries

12. Unsaturated fats Plant, vegetable & fish fats
liquid at room temperature
the fat molecules don’t stack tightly together
Better choice in your diet

13. Saturated vs. unsaturated

14. Other lipids in biology
Cholesterol
good molecule in cell membranes
make hormones from it
including sex hormones
but too much cholesterol in blood may lead to heart disease

15. Other lipids in biology
Cell membranes are made out of phospholipids
forms a barrier between the cell & the outside

16. Other lipids in biology
Phospholipids
heads are on the outside touching water
“like” water
tails are on inside away from water
“fear” of water

17. What you absolutely MUST know!
Lipids are fats
Lipids provide a source of energy for periods of low glucose availability
The cell membrane is composed of phospholipids, a type of lipid.
Another name for cell membrane is the phospholipid bilayer.
A triglyceride is made up of glycerol and 3 fatty acids.
Saturated fats can clog your arteries.
