The main â¦ functions of lipids are energy storage, as structural components of cell membranes, and as important signaling molecules.ipids have six major functions. They store energy, they are a  shock absorber, they are structural components in cell membranes,  they are precursors of hormones, they are â¦ insulation, and they aid  in the absorption of vitamins.
Examples of this function are their uses in cellular plasma and organelle membranes. Lipids have the ability to allow two layers of the membrane to develop. As a result, the cell is able to control what kinds of substances form across the walls of the cell.They are important in maintaining the structures of cells and providing a source of fuel to the body. Lipids come in the form of fatty acids, waxes, steroids and neutral fats.They can also be in compound form, which occurs when the lipids combine with another chemical compound. Under the latter category are lipolipids, glycolipids, and phospholipids. 1 person found this useful.ipids come in the form of fatty acids, waxes, steroids and neutral fats.
