Question 1

Phospholipids are common in sauces and creams. and are emulsifiers. True or False.

Answer 1

True

Question 2

What are phosphilipids?

Answer 2

Like triglycerides, phospholipids have a glycerol backbone. But unlike triglycerides, phospholipids
only have two fatty acid molecules attached to the glycerol backbone. In place of the third fatty
acid chain, phospholipids have a phosphate group. This unique structure makes one end of
phospholipids water-soluble and the other end fat-soluble.

Question 3

What are Sterols?

Answer 3

complex
molecules that contain interlinking rings of carbon atoms, with side chains of carbon, hydrogen,
and oxygen attached. Cholesterol is the best-known sterol.

Question 4

Cholesterol is bad for you and you want as little as possible

Answer 4

False. Cholesterol has some benefits to the body and you want it in moderation but you still need it.

Question 5

If each available carbon bond holds a hydrogen atom, we call this a

Answer 5

saturated fatty acid
chain.

Question 6

When one or more bonds between carbon atoms are a double bond (C=C),
that type of fatty acid is called an

Answer 6

unsatured fatty acid

Question 7

When the hydrogen atoms are
bonded to the same side of the carbon chain, it is called a cis fatty acid. True or False

Answer 7

True.

Question 8

When the hydrogen atoms
are attached on opposite sides of the carbon chain, what is formed

Answer 8

A trans fatty acid

Question 9

most trans fatty acids are not found naturally in foods but are a result of a
manufacturing process called partial hydrogenation. True or False

Answer 9

True

Question 10

partially hydrogenated oils are no longer considered “Generally
Recognized as Safe” or GRAS as a food additive. True or False

linolenic acid (ALA) and linoleic acid.

Answer 12

18 carbons long

Question 13

What are Eicosanoids

Answer 13

Eicosanoids are powerful hormones that are involved in the
regulation of many important body functions including clotting, inflammation, and blood
pressure control.

Question 14

The small droplets of fat surrounded
by bile are called

Answer 14

micelles

Question 15

The carriers of
triglycerides and cholesterol are called

Answer 15

lipoproteins. Lipoproteins are made of
phospholipids and proteins.

Question 16

the digested monoglycerides and fatty acids are reassembled into
triglycerides and phospholipids and packaged in the lipoprotein called a

Answer 16

chylomicron

Question 17

Name the different lipiproteins

Answer 17

very low-density
lipoproteins (VLDL) and high-density lipoproteins (HDL). Low-density lipoproteins (LDL)

Question 18

What is glycogen?

Answer 18

stored energy

Question 19

Does muscle weigh more than fat?

Answer 19

No it’s the same but muscle can take up more space
