What You Need to Know:


You should be able to:

  1. explain how to make a lipid (triglyceride),
  2. know the major types of lipids, their functions, and how they differ from the other lipids,
  3. distinguish between a saturated and unsaturated fatty acid,
  4. know what constitutes a fatty acid,

Exercises: Fill in the Blank.

  1. The building blocks of lipids are and
  2. When a fatty acid has every possible space taken up by hydrogen atoms (all single bonds between carbons) it is referred to as a fatty acid. (saturated or unsaturated)
  3. Glycerol + 3 fatty acids with the removal of water from each by condensation synthesis results in the formation of this type of lipid.
  4. Identify the structure of the lipid to the right.








  5. The name of the phospholipid found in the Schwann cell is .
  6. are recently discovered lipids that seem to have a variety of functions in the body; i.e. stimulation of inflammation, regulation of blood flow to certain organs, regulate onset of labor.
