Assess the importance of TAGs as an energy dense store for humans
- Triglycerides are very dense stores for energy and are non-polar, so they weigh less and are stored anhydrously in the body, unlike carbohydrates.
- In mammals, TAGs are most commonly found in the cytoplasm of fat cells.
- One gram of anhydrous fat stores more than six times the energy that a hydrated glycogen can store.
- They can yield more than two times the amount of energy in kJ after being oxidised than carbohydrates.
