1. Why do fatty acids provide a rich source of stored chemical energy for cells?
Because they are highly reduced

10. 2 classifications of fatty acid lipids
Storage lipids Membrane lipids
11. 3 type of lipids that dont contain fatty acids
CholesterolVitamins Pigments
12. How do many carbons do fatty acids typically contain?
Between 4-36
13. Which type of fatty acids have one double bond?
Mono saturated
14. Which type of fatty acids typically have more than one double bond?
Polysaturated
15. Which type of fatty acids have no double bonds?
Saturated
16. Why is it called omega 3 fatty acids?
Because the double bond is at the 3rd carbon
