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

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

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

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

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

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

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