1. Carries the maximum number of hydrogen atoms Saturated Fatty Acid (ex. Stearic
and contains only single bonds between the carbon Acid)
atoms
2. A fatty acid that lacks hydrogen and has at least one Unsaturated Fatty Acid
double bond (Olive and Canola Oil)
3. Has two or more carbon to carbon double bonds; Polyunsaturated Fatty Acid
lacks four hydrogens and has two double bonds
(Vegetable Oils)
4. Unsaturated Fatty Acids have how many double at least one
bonds?
5. Saturated Fatty Acids have how many double none, only single bonds be-
bonds? tween carbon atoms
6. Polyunsaturated Fatty Acids have how many double two or more carbon - carbon
bonds? bonds
7. The presence of at least one _______ makes a fat double bond
unsaturated?
8. Fatty Acids always have an even number of _______ carbons
?
9. Triglycerides consist of a glycerol and _______ ? three fatty acid tails
10. Which fatty acid tends to be solid at room temp and saturated, unsaturated
which is liquid at room temp?
11. What influences the stability of a fatty acid? the degree of saturation
12. Phospholipids are ______ in both fat and water. soluble

13. Phospholipids are ________ in the food industry. emulsifiers
14. What is the best know phospholipid? lecithin
15. Food sources of phospholipids: eggs, liver, soybeans, wheat
germ and peanuts
16. What do phospholipids do? part of the cell membrane, sus-
pend fat in the blood/body flu-
ids and help vitamins and hor-
mones pass in/out of cells.
17. First step to lipid digestion in the small intestine. Fat enters the small intestine
and triggers cholecystokinin
(CCK) to be released.
18. Second step to lipid digestion in the small intestine. CCK signals the gallbladder to
release bile, which acts as an
emulsifier.
19. Third step to lipid digestion in the small intestine. Pancreatic lipase (enzyme) di-
gests the fat.
20. What happens to the bile after lipid digestion in the It is reabsorbed into the blood
small intestine. and recycles to the liver.
21. Essential Fatty Acids Omega-6 and Omega-3
22. Omega-6 Essential Fatty Acid linoleic acid
23. Omega-3 Essential Fatty Acid linolenic acid
24. Obtain essential fatty acids directly from food such vegetable oils, seeds, nuts and
as: fish/seafood
