Now, let's move on to the second type of glycoprotein that we'll find inside our body. And this is known as erythropoietin, or EPO. Now, urethropoietin is a glycoprotein, and the protein component basically consists of an amino acid sequence of 165 amino acids. And four of these amino acids are actually glycosylated. So three of these amino acids are asparaging amino acids, and that means we have the N glycocitic bonds, and one of these amino acids is the Serene amino acid, and that means we have the O glycocitic bond. And so this brown section, which actually looks like a bunny, this brown section is the protein component of erythropolietin.
