Finally, we can also undergo the process of phosphorylation. We can add these phosphoryl groups onto our amino acids. In fact, many different types of cellular processes that take place inside our cells and inside our body use the phosphorylation as a way to turn on and off these different types of cell processes. For example, epinephrine, a hormone, and a newer transmitter can act on the serene and three anion amino acids by phosphorylating them. And that can turn on or off many different types of molecules and reactions of processes that exist inside our body. For example, insulin, which is a molecule that is used to regulate the amount of glucose found inside our body, inside our blood functions via this process.
