A
- 3 fatty acids bonded to glycerol with an ester bond
- 3 condensation reactions
4
Q
properties
A
- insoluble
- polyunsaturated
- long hydrocarbon chain store lots of energy long term
5
Q
functions
A
- source of energy
- store of energy
- insulation
- protection
6
Q
phaspholipid
A
- phosphate bonded to glycerol and 2 fatty acids
- head hydrophilic and interacts with water
- tails hydrophobic and hate water
- creates 2 layers to make cells double membranes
