Instructions
In this worksheet, you will explore the structures of fatty acids, triglycerides, and phospholipids. Follow the steps below to answer the questions regarding their composition and structures. Make sure to refer to the provided diagrams and illustrations for a better understanding.
Step 1: Fatty Acids
Examine the structures of saturated and unsaturated fatty acids. List the main differences in their structures below.
Step 2: Composition of Fatty Acids
Identify the atoms that are present in both saturated and unsaturated fatty acids. Write them below.
Step 3: Triglycerides
Triglycerides are formed from glycerol and fatty acids. Describe how many fatty acids are typically involved in the formation of a triglyceride and the type of bonds formed.
Step 4: Composition of Triglycerides
List the atoms that are found in triglycerides. Consider both the glycerol and the fatty acids.
Step 5: Phospholipids
Explore the structure of phospholipids. What makes phospholipids unique compared to triglycerides? Discuss their hydrophilic and hydrophobic parts.
Step 6: Composition of Phospholipids
What atoms are present in phospholipids? Include any additional groups they may have.
Step 7: Comparison Table
Create a table to compare fatty acids, triglycerides, and phospholipids in terms of structure, atom composition, and functions. Use the spaces below to create your table.
Once you have completed the steps, review your answers and ensure you have captured all relevant information about each type of lipid. Good luck!
