Concept #1: Sphingolipid Recap

Concept #2: Reviewing Classes of Sphingolipids

Practice: Which of the following is TRUE of sphingolipids?

A) They always contain glycerol and fatty acids. 

B) They may be charged, but are never amphipathic.

C) Phosphatidylcholine is a typical sphingolipid. 

D) They contain only one esterified variable fatty acid. 

E) Cerebrosides, globosides and gangliosides are sphingolipids. 

Example #1: Appropriately match each of the following six lipid molecules with one of the listed types of lipids:

Practice: Match the following lipid types with the correct description.

A) Fatty acid. _____                                     1. Membrane lipids with a glycerol backbone.                   

B) Triacylglycerol. _____                             2. Phospholipid especially common in nerve cells.

C) Phospholipid. _____                               3. One of the simplest forms of a glycolipid.

D) Sphingosine. _____                                4. Lipids covalently attached to carbohydrate groups.

E) Glycerophospholipid. _____                  5. Chains of hydrogen-bearing carbon atoms with a carboxylic acid.

F) Sphingomyelin. _____                            6. Complex glycolipids with a sialic acid residue. 

G) Glycolipid. _____                                    7. A complex amino alcohol backbone for membrane lipids. 

H) Cerebroside. _____                               8. Major class of membrane lipids. 

I) Ganglioside. _____                                  9. Long-term storage form of fatty acids.
