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.
Energy storage and cell membrane formation are the two most prominent functions of lipids in the body, but there are other functions. It is believed that lipids play an important role in cellular signaling, the process by which various biochemical processes are initiated or stopped.any different types of molecules in the body, such as fats, waxes, and fat-soluble vitamins, fall into the category of lipids.. Energy storage is the most common of the many functions of lipids, though they can also provide cellular structure or act as signaling molecules.
