2

What are 6 examples of sources of fat?

Pizza
Sandwiches
Burgers
Cakes
Cookies
Doughnuts

3

What are triglycerides?

Main dietary lipid

4

Define Hydrophobic molecules

Nonpolar molecules that repel the water molecules

5

Is triglycerides hydrophobic?

Yes

6

What are triglycerides made out of? 2 things

A glycerol backbone
3 fatty acids

7

What are 3 things fatty acids vary in?

They have different:
Length
Degree of saturation
Geometric organization

8

What does degree of saturation in a fatty acid mean?

The number of hydrogen atoms attached to the fatty acid

9

What is an example of a saturated fatty acid?

Palmitic acid

10

What is an example of a monounsaturated fatty acid?

Oleic acid (omega-9)

11

What are two examples of a polyunsaturated fatty acid?

Linoleic acid (omega-6)
Alpha-linolenic acid (omega-3)

12

What are two things at each end side of the fatty acid?

Methyl or omega end
Acid group

13

What is a difference between saturated fatty acid and unsaturated fatty acid?

Saturated fatty acids have no double bonds and that's why its most saturated with hydrogens

14

What is the difference between linoleic acid (omega-6) and alpha-linolenic acid (omega-3)?

Alpha-linolenic acid (omega-3) has more double bonds than linoleic acid (omega-6)

15

Where can longer chain of saturated fatty acid be commonly found in? 2 things

Solid at room temperature
Animal foods

16

What does high consumption of long chain saturated fats do? 2 things

Increase the risk of cardiovascular disease
Higher LDL, lower HDL

17

Where can medium chain saturated fatty acids be found in?

Tropical oils

18

What is consider a medium chain saturated fatty acids?

A fatty acid with 6-12 carbons

19

What is consider a short chain saturated fatty acids?

A fatty acid with less than 6 carbons

20

What does high consumption of medium chain saturated fats do? 2 things

Improves body composition
Increase LDL and HDL

21

How is short chain saturated fatty acids produced?

It is produced when dietary fibre is fermented in colon

22

What is the effect of high consumption of short chain saturated fatty acids? 2 things

Promote colonic health
Reduce risk of cardiovascular disease

23

What are two similarities between medium and short chain saturated fatty acids?

Both are absorbed through the portal vein and both do not go into the lymphatic system, which makes them less likely to be stored.

24

What is the difference between the long chain saturated fatty acids and the other chains of saturated fatty acids?

Only the long-chain saturated fatty acids go through lymphatic system

25

What is considered a unsaturated fatty acids?

If it has one or more double bonds

26

Where are unsaturated fatty acids found in? 3 things

Liquid at room temperature
Plant based foods
Fish

27

What is considered a monounsaturated fat?

1 double bond

28

What is considered a polyunsaturated fat?

2 or more double bonds

29

What does consumption of monounsaturated fat do?

Positive effects on LDL cholesterol

30

Are humans able to synthesize polyunsaturated fatty acids?

No
