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.
These are just a few examples of the many, many functions of proteins. 3.Lipids are long term energy storage in comparison to carbs, which are for short-term usage. *Structuring cell membranes. The cell membrane constitutes a barrier for the cell and controls the flow of material in and out of the cell. *Energy storage.Triglycerides are an efficient form of energy storage that can be mobilized when fuel is needed. *Transmission of information in cells (signal transduction).Lipid hormones, like steroids and eicosanoids, also mediate communication between cells.riglycerides are an efficient form of energy storage that can be mobilized when fuel is needed. *Transmission of information in cells (signal transduction).
