Q
What makes up a lipid, and what reaction brings them together?
A
Glycerol and fatty acids, bonded with a condensation reaction
1
Q
What are lipids?
A
Fats and oils
2
Q
What is left over from the reaction?
A
Water
3
Q
What is the opposite of a condensation reaction?
A
Hydrolysis
4
Q
Which bond is formed As a result of the lipid being formed?
A
An ester bond. This is the bond of an oxygen, a carbon, and a double bonded oxygen
5
Q
What is the name for the product when one glycerol and three fatty acids bond?
A
A triglyceride
6
Q
What depicts the properties of the lipid?
A
The length and saturation of the carbon chains
7
Q
Saturated chains:
A
- straight chains
- close together, so stronger intermolecular forces
- causes a higher melting point
8
Q
Unsaturated chains:
A
- kinky chains
- molecules can’t get very close to each other so weaker intermolecular forces
- causes a lower melting point
