- Select the correct statement about unsaturated fatty acids: 1. Unsaturated fatty acids have extra nitrogen atoms in their hydrophobic tails compared to saturated fatty acids 2. Unsaturated fatty acids have multiply bonded carbons in their hydrophobic tails compared to saturated fatty acids which have only single bonded carbons 3. Unsaturated fatty acids have no bends in their hydrophilic fatty acid tails 4. Unsaturated fatty acids have relatively more hydrogen atoms in their hydrophobic tails compared to saturated fatty acidsarrow_forwardWhich of the following statements is/are true? 1. Sphingolipids all have a palmitate derivative that is ester-linked to the sphingosine backbone. 2. The addition of cholesterol will always lead to an increase in the rigidity of a lipid bilayer. 3. Glycolipids may have a sphingosine or a glycerol backbone to which a sugar moiety is attached. 4. All lipid molecules are characterized by the presence of a carboxylic acid functional group.

- Which of the following is true of unsaturated fats?(A) They are more common in animals than in plants.(B) They have double bonds in their fatty acid chains.(C) They generally solidify at room temperature.(D) They contain more hydrogen than do saturated fats havingthe same number of carbon atomsarrow_forwardYou are studying the properties of an Antarctic fish and a tropical fish. What differences might you observe in the composition and/or structure of their lipids? Explain. **Hint: membranes should be flexible a balance between providing structure but also remaining fluid. For these applications, consider what type of lipids (length, number of double bonds) are needed to maintain that balance. You will not have to name the lipids, but describe their shape and structure. Also keep in mind that the hydrophobic interactions between the fatty acids themselves are the most crucial factors to fluidity and that backbones (glycerol vs. sphingosine) and head groups (e.g. phosphates, sugars, cholines, etc.) will not significantly alter fluidity.arrow_forwardWhat structure(s) contain(s) ribose?arrow_forward
