For example, inside our muscle cell, we basically break down branch chain amino acids such as leucine, isoleucine, and valine. So let's take a look at how we actually break down amino acids. Now, we have different ways by which we break down different amino acids, but let's begin by focusing on this two step process here. So essentially, the goal in the breakdown of amino acids is first we have to remove that amino group from that amino acid to form our ammonia. The ammonium ultimately is fed into the urea cycle, and that removes that ammonium from the body and the leftover carbon skeleton that we have left over. After this process occurs, that is used to form energy molecules, and we'll talk about that in electra to come.
