What is the function of lipids in the cell membrane?
Lipids are insoluable, fatty materials the cell can either use to construct membranes from or use as a source of energy in the form of fat. Cell membranes are double sheets of phospholipids. The water attracting phosphate groups coat the inside and outside of the membrane with the fatty lipid groups sandwiched between. These membranes can form small compartments inside cells known as vacoules. Some vacoules store lipids as an energy source. The best example is the yolk of an egg.
