Homework Answers
Glycolipids differ from sphingolipids in that they contain no Phosphate.
Sphingolipids are member of a class of lipids containing the organic aliphatic amino alcohol sphingosine or a substance which is structurally similar to it.
Glycolipids are large group of sphingolipids, so called because they contain one or more molecules of sugar (glucose or galactose)

How are lipid bilayers formed? What is their fluidity dependent on? Group of answer choices: - Hydrophobic interactions are the driving force of forming bimolecular sheets of lipids spontaneously. Due to the hydrophobic effect, any tears in the lipid bilayer cause it to spontaneously rearrange to eliminate the free edge. Membrane fluidity depends on the percentage of unsaturated fatty acids. - Hydrophobic interactions are the driving force of forming bimolecular sheets of lipids spontaneously. Due to the hydrophobic effect, any...
