Skill 20.3 Identifying everyday applications of organic reactions 

Recognizing and distinguishing the structures of the major classes of biomolecules (proteins, lipids, carbohydrates, nucleic acids) 

Lipids typically have large hydrocarbons as part of their structure and are insoluble in water. Animal fats and vegetable oils are complex lipids called triacylglycerides. These molecules contain three ester groups. 

Simple lipids such as cholesterol (shown below) do not contain ester groups  

Many lipids like the fatty acids above have a long non-polar hydrocarbon tail region and a small polar head region. The hydrocarbon region of the molecule is hydrophobic ( water-hating ), and the polar region is hydrophilic ( water-loving ).
