Which statement is FALSE about cholesterol?
Practice: Fatty Acids
What portion of a fatty acid, CH3(CH2)nCOOH, is considered hydrophilic?
Lipid rafts are regions of membrane which have different constituent lipids, and which tend to be less fluid than surrounding regions of membrane. Lipid rafts are enriched in sphingomyelin, which is similar to phospholipids, and which has a fatty acid tail. Based on what you know about lipid rafts, predict the characteristics of the sphingomyelin fatty acid tail.

In your own words, explain how cholesterol modulates membrane fluidity.
Lipid rafts are regions of membrane which have different constituent lipids, and which tend to be less fluid than surrounding regions of membrane. Lipid rafts are enriched in sphingomyelin, which is similar to phospholipids, and which has a fatty acid tail. Based on what you know about lipid rafts, predict the characteristics of the sphingomyelin fatty acid tail.
