What exactly do lipids do for you? Lipids store energy and act as structural components of cell membranes. They are used in cosmetics, the food industry, and nanotechnology. Major lipid groups include fats, phospholipids, steroids, and waxes.  Fats, also known as triglycerides, are a subgroup of lipids. They are composed of three fatty acids and glycerol and are essential in many of our bodies' daily functions. 

Creative Applications

  1. Consider the texture of fat. How is it beneficial to your organs? 
  2. Lipids are generally insoluble in polar substances such as water. How is this property beneficial to humans and other animals?
  3. How do lipids affect our metabolism?
  4. What would happen if we didn’t consume enough fat?
