There are different types of nutrients to be found in food, but they can be roughly divided into: sugars (carbohydrates), proteins and fats (lipids). Your liver produces bile that is stored in the gallbladder and released to the duodenum (part of the small intestine). As far as I remember my biology classes bile facilitates digestion by breaking large lipid (fat) droplets into smaller ones. Thanks to that it increases the total surface area in contact with digestive enzymes (lipases). So much for the theory, but I always wondered if that’s true.
Use Julia to demonstrate that the total surface area of a few small lipid droplets is actually greater than the surface area of one big droplet. Of course, the big droplet and small droplets should contain the same volume of lipids.
