But once those fats actually end up in the target liver and fat cells, when they are released into our blood system once again, then they travel in our blood via albumin. So, albumin is the protein carrier that carries fatty acids inside our blood plasma. Now, earlier, I mentioned that arachylomycrane is the largest type of lipoprotein. Now, lipoproteins are basically molecules that contain protein components as well as lipid components. And lipoproteins are often used to transport fats inside our blood plasma, as we just saw. And there are five different categories of lipoproteins.
