This question doesn't make much sense. There are more than three amino acids found in proteins. There are about 20. Some amino acids are more common than others, for example glutamine is one of the most common found in humans.
Proteins are formed from the basic units called as amino acids. There are 20 amino acids in the body of human being. You have over 300 amino acids found in the nature.
Proteins are polymers. The monomers of proteins are amino acids.
The only element that is not found in any of the 20 essential amino acids but is found in nucleic acids is Phosphorus. It is found in the "Sugar-Phosphate backbone" of nucleic acid but is not found in any of the essential amino acids. Many proteins interact with phosphate groups but they do not make up the protein.
Single amino acids are found in the cytoplasm of the cell. They are mainly useful in protein synthesis, although they have other uses.

Proteins consists of amino acids
Amino acids are the building blocks of protein. They are found in foods like milk, eggs and meat. They also can be found In a variety of plants.
Proteins are formed from the basic units called as amino acids. There are 20 amino acids in the body of human being. You have over 300 amino acids found in the nature.
The various amino acids are distinguished by the substitution on the central carbon atom. All amino acids feature an amine group and a carboxylic acid.

Proteins are polymers. The monomers of proteins are amino acids.
There is a great degree of variability in the number of amino acids per protein. An answer to another question on WikiAnswers lists the shortest protein as 8 amino acids. According to the National Center for Biotechnology Information, the longest protein found in a sequenced genome is a "parallel beta-helix repeat-containing protein" in the organism Chlorobium chlorochromatii, this protein is 36,805 amino acids long.A protein may consist of as many as 5,000 amino acid molecules.
Proteins, large and complex biomolecules, are made of amino acids. The amino acids react together to form longer chains called polypeptides. The so-called primary structure of a protein is determined by the specific amino acid sequence unique to every protein, whereas its secondary structure depends on how the polypeptide chain is coiled. The tertiary structure of a protein is finally how the protein looks in 3D. And if several polypeptides interact, forming an even bigger structure, then the protein is said to have a quaternary structure. There are essential and non-essential amino acids. The non-essential ones are made in the body, whereas the essential amino acids must be found in the diet.
Because amino acids can be arranged in many different combinations, it's possible for your body to make thousands of different kinds of protein from just the same 20 amino acids.The simplest protein of life, Rybonuclease, contains 124 amino acids. The "average" protein, though, contains several thousand amino acids, but those several thousand are only comprised of about about 20 different kinds of amino acids.
There are twenty common protein amino acids in your body, of which half can be formed in the cells. The remainder need to be consumed in our diet, as our body cannot make them, yet they are still vital. There are 2 other amino acids very ocassionally used in proteins (only one in humans) meaning that are 21 different protein amino acids in humans. Some biological pathways use other types of amino acids not found in proteins. There are at least six additional ones found in humans, but it would be difficult to determine an exact number.
The only element that is not found in any of the 20 essential amino acids but is found in nucleic acids is Phosphorus. It is found in the "Sugar-Phosphate backbone" of nucleic acid but is not found in any of the essential amino acids. Many proteins interact with phosphate groups but they do not make up the protein.
