But let's suppose we have all the proteins that we want, and we have all the nucleotide bases that our cells can actually use. What happens to any extra leftover amino acids? Well, you might be thinking we can store those amino acids for later use. 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.
