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.
Therefore, Lipids are not soluble in water but are soluble in nonpolar solvents (ex: benzene and chloroform). Lipids have several functions in biology. Digestion of triglycerides yields glycerol and fatty acids, which are subsequently used as fuel. Additional biological functions include: constructing cell membranes, storing energy, and as signaling molecules. Lipids can form bonds to proteins and carbohydrates forming lipoproteins and lipopolysaccharides.
