Protein Structure. Proteins are made up of structures called amino acids. There are a total of 20 amino acids, some of which are essential and some of which are nonessential. Essential amino acids are those that you must consume in your diet because your body cannot make them. Nonessential amino acids are those that your body can produce, so they are not as vital in the diet. The way the amino acids come together determines what type of protein is made.
