For example, phospholipids and cholesterol are found in our membrane, while our fatty acids and triglyceride, triglycerides is the form that we store our fats inside our adipose cells. And fatty acids are those lipids that we use to actually break down and for ATP. So because lipids do not actually dissolve in water, and because the majority of the body and the cells are composed of water, that means lipids do not dissolve in our blood. They do not dissolve in our cytoplasm, the cell. And so what that basically means is when we ingest lipids, they're going to aggregate together. They're going to basically form these bundles, these fat bundles.
