What functions do fats and lipoids perform? What physical properties determine the construction function of phospholipids?

Fats and lipoids perform the following functions:
1. Plastic. Phospholipids form cell membranes.
2. Energy. During the oxidation of 1 g of fat, 38.9 kJ (9.3 kcal) of energy is released.
3. Fats are solvents for hydrophobic substances, such as vitamins (A, D, E).
4. Reserve. Fat inclusions of a drop of fat in the cytoplasm of a cell.
5. Thermoregulation. Due to poor thermal conductivity, adipose tissue can serve as a heat insulator.
6. Protective. Loose adipose tissue during mechanical damage protects the underlying organs from injury.
