And finally, what the liver cells can also do is if we eat too much sugar or too much protein, what the liver cells do is they transform the sugars or the protein into fat. Now, let's move on to our protein, the final type of macromolecule that we ingest into our body and that our body actually needs to survive. So we actually ingest ten essential amino acids that our body cannot actually manufacture, but the other ten none essential amino acids are produced by the liver cell. So the liver can produce the ten non essential amino acids. And the liver can also use the 20 total amino acids to basically produce important types of proteins, such as, for example, albumin and fibrinogen. So albumin is the protein carrier of fatty acids in the blood plasma, while fibrinogen is an important type of enzyme, an important type of protein that is involved in the blood clotting cascade, as we'll see in a future lecture.
