1 Lipid Review 1

2 1. What are the four examples of lipids? 2

3 1. Saturated 2. Unsaturated 3. Sterol 4. phospholipid 3

4 2. What are the three functions of lipids? 4

5 1. Energy storage 2. Chemical messengers 3. Form biological membranes 5

6 3. What are the two components or parts of a lipid? 6

7 1. Glycerol 2. Fatty acid 7

8 4. What is a fatty acid made from? 8

9 Long hydrocarbon chain with a carboxyl group 9

10 5. What is a glycerol made from? 10

11 3 carbons and 3 OH groups 11

12 6. How can you identify a lipid? (What is the ratio of carbon, hydrogen, and oxygen.) 12

13 1 carbons for every 2 hydrogen and very few oxygen atoms 13

14 7. What type of bonds are between the carbon atoms in a saturated fat? 14

15 All single bonds 15

16 8. At room temperature are saturated fats solids or liquids? 16

17 solids 17

18 9. Where do we find saturated fats? (What type of foods?) 18

19 Meats and dairy 19

20 10. What do you have to have between carbon atoms to form an unsaturated fat? 20

21 At least one double bond 21

22 11. What type of fat forms when more than one double bond is found between the carbon atoms? 22

23 polyunsaturated 23

24 12. What happens structurally in an unsaturated fat that causes it to be a liquid at room temperature? 24

25 It gets a kink or a bend in the molecule, this prevents them from being packed closely together. 25

26 13. What do sterols do in the body? 26

27 Chemical messengers 27

28 14. Write an example of a sterol. 28

29 Cholesterol 29

30 15. What do phospholipids form? 30

31 Bilayers for membranes 31

32 16. What does hydrophobic mean? 32

33 water fearing 33

34 17. What does hydrophilic mean? 34

35 Water loving 35

36 18. What type of molecule is shown below? 36

37 carbohydrate 37

38 19. What type of molecule is shown below? 38

39 Unsaturated fat 39

40 20. What type of molecule is shown below? 40

41 Saturated fat 41
