- Lipids
- consist of
- Carbon
- Hydrogen
- Oxygen
- (Phosphorus)
- insoluble in water
- triglycerides
- condensation reaction
- 1 glycerol
- 3 fatty acids
- saturated
- no C=C bonds
- all C-H bonds
- higher MP
- solid at room temperature
- Unsaturated
- C=C bonds
- plant fats or oils
- Lower MP
- liquid at room temperature
- saturated
- ester bond formed
- esterification
- water is released
- good of organisms in dry environments
- Camels -store fat in humps
- good of organisms in dry environments
- Functions
- thermal insulation
- reduce heat loss
- protect vital organs
- buoyancy
- store excess energy
- energy source
- store 2x energy as carbohydrates
- thermal insulation
- condensation reaction
- Phosphoplipids
- condensation reaction
- 1 glycerol
- 2 fatty acids
- 1 phosphate
- extra electrons so have a negative charge
- ester bonds formed
- Hydrophilic head
- phosphate
- attracted to water/polar molecules
- hydrophobic tail
- fatty acid
- repels water/polar molecules
- functions
- formation of cell membranes
- selectively permeable barrier
- waterproof
- electrical insulation
- produces hormones
- formation of cell membranes
- condensation reaction
- cholesterol
- steroid alcohol
- hydrophilic hydroxyl
- made of carbon rings
- doesnt consist of glycerol and fattu acids
- functions
- maintains stability and regulates fluidity of membrane
- precursor to enzymes to activate
- produce steroid hormones
- oestrogen
- testosterone
- consist of
