- Lipids
- Triglyceride (mainly used as energy storage molecules)
- One molecule of glycerol with three fatty acid tails
- Tails make it insoluble in water as they are hydrophobic
- Tails are hydrocarbon
- Tails contain a lot of chemical energy - lots released - more energy per gram in comparison to carbohydrate
- Cholesterol
- Hydroxyl group
- Slightly soluble in water (polar hydroxyl) but insoluble in blood - lipoproteins
- Fit between phospholipid in membranes
- MORE RIGID
- Steroids, bile
- Phospholipids (in cell membrane)
- Hydrophobic tail
- Hydrophilic phosphate head
- As it is ionised
- Forms bilayer
- Centre of bilayer is hydrophobic
- Triglyceride (mainly used as energy storage molecules)
