Both triglycerides and phospholipids contain glycerol and ester bonds, and their fatty acids can be saturated or unsaturated. However, phospholipids also contain phosphorus, have a hydrophilic and hydrophobic region, and can form bilayers, unlike triglycerides which are entirely hydrophobic.
Vergelijk en contrasteer de structuur en eigenschappen van triglyceriden en fosfolipiden. [5 punten]
| Front | Compare and contrast the structure and properties of triglycerides and phospholipids. [5 marks] |
|---|---|
| Back | 1. Both contain ester bonds (between glycerol and fatty acid); 2. Both contain glycerol; 3. Fatty acids on both may be saturated or unsaturated; 4. Both are insoluble in water; 5. Both contain C, H and O but phospholipids also contain P; 6. Triglyceride has three fatty acids and phospholipid has two fatty acids plus phosphate group; 7. Triglycerides are hydrophobic/non-polar and phospholipids have hydrophilic and hydrophobic region; 8. Phospholipids form monolayer (on surface)/micelle/bilayer (in water) but triglycerides don’t; |
