"Webbmore. The most common amino acids are leucine, serine, lysine, and glutamic acid. These acids each make up around 6-7% of the protein, compared to the normal 3-4% of other amino acids. However, each type of protein is different and is synthesized with different acids, so it's hard for us to measure the most common. " - Protein structure bonds explained
