CHEM210 Module 5 Exam questions with answers correct
1. lipids: What serve as the fat energy molecules in most organisms and are also the basis for the structures of cell walls?
2. lipid: What is an organic molecule that dissolves in a non-polar solvent?
3. fatty acids, triaglycerols, phosphoglycerides, sphingolipids, isoprenoid: What are the
five structures that lipids are classified as?
4. fatty acids: What consist of a long carbon chain containing a carboxylic acid functional group at the end?
5. 8 to 30: What does the length of fatty acids vary between?
6. no double bonds: What does a saturated fatty acid mean?
7. simplified notation system: What shows how many carbons and double bonds there are?
8. one or more double bond: What does unsaturated fatty acid mean?
9. polyunsaturated fatty acid: What contains two or more double bonds in a fatty acid chain?
10. omega system: What is the position of the double bond end opposite of the carboxylic acid group or said another
way, numbered from the -CH3 end of the molecule?
11. triacyglycerols: What are dense energy storages because they have long chains of carbon and hydrogen in the form
of fatty acid chains?

, 12. glycerol: What serves as the backbone of the triacyglycerol structure with three fatty acids attached via an acyl linkage?
13. oil: What is it called when lipids are liquid at room temperature?
14. fat: What is it called when lipids are solid at room temperature?
15. phosphoglycerides: What have glycerol as a backbone molecule, with two fatty acids attached to the first and second
carbons and a polar group attached to the third carbon?
16. molecular structure: What allows molecules to spontaneously form membrane bilayers with tails aggre- gating
together?

18. defining blood type and creating myelin sheath: What are two functions of shingolipids?
19. isoprene: What is a five carbon, one double bond molecule that serves as the starting material for many lipid molecules?
20. vitamin A, K, cholesterol, and carotenoid: What four things are made of isoprene?
21. vitamin K: What is a fat-soluble vitamin essential for blood coagulation?
22. cholesterol: What helps to maintain the fluidity of cellular bilayer?
23. cellular membranes: What separate the components of the cell from the outside environment?
24. integral proteins: What are proteins firmly associated with membrane?
