What makes the lipid macromolecule different
They are NOT polymers
Lipids are heterogeneous which means…
They are all structurally different from each other
Are lipids hydrophilic or hydrophobic
Hydrophobic
Three functions of lipids
Energy
Structure
Regulatory
What lipids can be found in cell membranes
Cholesterol and phospholipids
