So in the same way that we can store glucose as glycogen, and we can store extra fatty acids as triglycerides, can we store extra amino acids inside our cells? And the answer is simply no. Our cells do not have a way to actually store any excess amino acids. And so what must happen to these extra amino acids is they must be broken down. Now, the majority of the breakdown of amino acids occurs inside our liver. But other cells, such as muscle cells, can also break down amino acids.
