1. Identify the monomer of a lipid, and draw the approximate structure.
2. How can you differentiate between both carbohydrates and lipids if
they both contain only carbon, hydrogen, and oxygen?
3. What happens when there is a double bond in the fatty acid tail of a
lipid?
4. Differentiate between saturated and unsaturated fats. Be sure to
include structural, source, and other differences.
5. What is the type of bond that links these fats together?
6. What is the process that breaks apart esther linkage?
7. Identify four functions of lipids (be specific).
8. I thought that carbohydrates stored energy, what is so different
between that energy and the energy stored in fats?
9. Draw the lipid that is found in the membranes of cells, and identify the
hydrophilic and hydrophobic portions. Why is this so important to cell
function?
10.

why we need them.
