“What is your fat made out of?”
Everyone has fat on their bodies, but have you ever wondered what it is made out of? Well, it turns out that body fat is composed of an interesting class of molecules called lipids. Lipids are molecules that contain hydrocarbons and are insoluble in water due to their non-polar structure. This composition also makes them hydrophobic. These liquids form an essential part of a creature’s biology. In fact, we can obtain a reasonable amount of lipids by consuming the fat of other animals.
