- Biochemistry
- Lipids
- Roles
- Energy storage, insulation, membranes, hormones, transport
- Polar func groups
- Saturated & Unsaturated hydrocarbon chains
- Insoluble in water
- Double bond = unsat
- Cis and Trans
- Hydrogenation
- Carboxylic acid
- Saturated & Unsaturated hydrocarbon chains
- Properties
- More Cs = higher MP
- More double bonds = Lower MP
