What properties do lipids have?

Lipids are organic compounds whose main component is fatty acids. Unlike proteins, carbohydrates, nucleic acids, lipids are not polymer molecules, they are not classified as macromolecules. They are slightly soluble in water, but soluble in ethers, gasoline, chloroform and some other solvents. The composition of lipids includes glycerin, and the acids in the composition can be saturated fatty acids, or unsaturated. Simple and complex lipids are secreted. Simple lipid molecules are composed of residues of fatty acids and alcohols. This group includes fats. They are stored in the form of droplets in the cytoplasm of cells and serve as a valuable source of energy. When they are split, 2 times more energy is released than when the same amount of glucose is split. Stocks of fat in the subcutaneous fat of mammals allows you to survive the adverse conditions associated with a lack of food and water. Especially this property of fats, accumulate in the body and, when broken down, secrete intracellular water, which is necessary for metabolic processes in the cell, is necessary for desert animals.
