22. Lipids
The different types of lipids are determined by the number of C-H bonds in the fatty acid chain.

23. Lipids C O H
Saturated Fatty Acid: maximum number of C-H bonds.

24. Lipids C O H
Unsaturated Fatty Acid: contains one double C-C bond.

25. Lipids O C H
Polyunsaturated Fatty Acid: many double C-C bonds.

26. Function of Lipids
Lipids store energy, due to their numerous C-H bonds.
Energy

27. Function of Lipids
Because they are insoluble in water (polar), lipids are found in animal cell membranes.

28. Function of Lipids
Send chemical messages in the form of hormones.
