So fatty acids are fuel molecules, and our cells store fatty acids in a form we call triglycerides or triathoglycerides. And this is what a triathoglycerol actually looks like. So we have three fatty acids, one, two, three, shown in blue, which which are basically attached onto this connecting molecule, this scaffolding molecule we call a glycerol. And together, this is what we call triathloglycerol or triglycerides. Now, inside our body, we essentially store potential energy in three types of macromolecules. So we have glycogen, which is a carbohydrate, we have proteins and we have triglycerides.
