Unit 5 Lipids

Question 1

Picture of saturated fatty acid

Answer 1

When all carbons in the chain are connected with a single bond, they results in “saturated fat” because the have the maximum about of hydrogen atoms possible (saturated with hydrogen).

Question 2

When the chain contains two carbons that are connected with a double bond, it results in “_________ ______” because it contains two fewer hydrogen atoms with the presence of the double bond.

Answer 2

Unsaturated fat, & also monounsaturated bc it’s just one double bond in fatty acid chain.

Question 3

A phospholipid contains what additional groups, & where are they located?

Answer 3

Phosphate & nitrogen group; opposite the fatty acid chain.

Question 4

The head of a phospholipid is polar or non-polar?

Answer 4

Polar (hydrophilic/water loving/water soluble)

Question 5

The fatty acid end of phospholipid is ___ _____, or _________.

Answer 5

Non polar, hydrophobic

Question 6

Phospholipids structurally form cell bilayers, true or false?

Answer 6

True

Question 7

Cholesterol is a steroid, true or false?

Answer 7

True

Question 8

A 4 carbon ring as a structural foundation is indication of what type of fatty acid?

Answer 8

Steroid (pic of steroid)

Question 9

Trans fats are _________, but bad for the body.

Answer 9

Unsaturated

Question 10

“CIS” formation of fatty acid has at least one set of double bonded carbon atoms with the hydrogen bonds on….

Answer 10

Same side of the double bonded carbon atoms.

Question 11

“Trans” formation of fatty acid has at least one set of double bonded carbon atoms with the hydrogen bonds on….

Answer 11

Opposite sides of the double bonded carbon atoms.

Question 12

Identify the red Carbon

Answer 12

Beta Carbon
