Lipids Flashcards
1
Q
The Two Types of Lipid
A
Triglyceride
Phospholipid
2
Q
Triglyceride
A
1x Glycerol
3x Fatty Acid Tails
Energy Store - Lots of bonds in Fatty Acids
Insulation - Thermal and Mechanical
Fatty Acid tails are Hydrocarbons
3
Q
Ester Bonds
A
Condensation reaction
Between Glycerol and a Fatty Acid
4
Q
Phospholid
A
1x Glycerol
2x Fatty Acid Tails - Hydrophobic
1x Phosphate containing group - Hydrophillic
5
Q
Emulsion Test
A
- Add Ethanol to sample
- Shake/mix vigorously
- Add Water
- Positive = Milky white Emulsion formed
6
Q
Properties of Triglycerides
A
Energy Storage Molecule
- Long Hydrocarbon tails contain lots of chemical energy
- Also insoluble
7
Q
Properties of Phospholipids
A
Bilayer of cell membranes
- As Phosphate group is Hydrophilic
- And Fatty Acid is Hydrophobic
