It depends on what you mean by "exist in nature".
Although there are only 20 amino acids coded for by the standard genetic code, plus 2 other oddities (selenocysteine and pyrrolysine) a lot more exist in nature. Currently there are over 500 (see http://www3.interscience.wiley.com/journal/106583994/abstract). Most of these do not occur in proteins or "free" in nature (i.e they are reaction intermediates not end products in biosynthetic pathways).
There are many more than the standard 22 proteinogenic amino acids that do occur in proteins. This is the result of post-transational modification where the amino acids in a protein are modified (often by the action of another enzyme). These can be simple modifications like methylation, or more elaborate ones like the addition of complex carbohydrates.
What else can I help you with?
Are Proteins linked amino acids that occur naturally in foods.?
Yes, proteins are composed of long chains of amino acids linked together by peptide bonds. These amino acids occur naturally in various foods, including meat, dairy, legumes, and nuts. When consumed, proteins are broken down into their constituent amino acids, which the body uses for various functions, including building and repairing tissues.
Are Proteins are linked amino acids that occur naturally in foods?
Yes, proteins are made up of long chains of amino acids, which are organic compounds that occur naturally in a variety of foods. These amino acids are essential for many bodily functions, including building and repairing tissues, making enzymes and hormones, and supporting immune health. Foods such as meat, fish, eggs, dairy, legumes, and nuts are rich sources of proteins. Thus, consuming a balanced diet helps ensure an adequate intake of these vital nutrients.
What are the monomers that make enzymes up?
Enzymes are proteins.Proteins are made up of amino acids
What class of biological molecule contains peptide bonds between the individual monomers?
Amino acids are joined by peptide bonds. A peptide bond is a covalent bond that forms between two amino acids when the carboxyl group (COOH) of one amino acid reacts with the amino group (NH2) of the other amino acid, resulting in a C-N bond, which is a peptide bond.

What organelle builds amino acids?
organells's are not directly responisble for amino acid synthesis. production of amino acids occur in the cytosol, but only when the organism criticly needs them!! Amino acids are primarily obtained by the breakdown of proteins and not produced from scratch. This is because it requires far too much energy in the reaction pathways for the sythesis of the amino acid, as well as the special enzymes that are needed to catylise these processes. the genes that code for the production of these enzymes are very rarely used.

Are there more than 20 amino acids in existence?
Yes, there are more than 20 amino acids in existence. While there are 20 standard amino acids that are commonly found in proteins, there are also non-standard amino acids that occur naturally or can be synthesized.
Is it true that Proteins are linked amino acids that occur naturally in foods.?
Yes, that is correct. Proteins are large biomolecules composed of amino acids that are essential components of all living organisms. They are found naturally in a variety of foods such as meat, fish, eggs, dairy, legumes, and nuts.

What must occur for amino acids in a protein bar to convet into protein your body cells?
There are no amino acids in protein bars. Amino acids are made up of strands of proteins. What happens is when food is digested, proteins are absorbed by special cells. These cells construct the proteins into an amino acid. They then are transfered to other cells, and disolve into them for energy.
How many monomers of proteins exist?
20
What are the monomers that make enzymes up?
Enzymes are proteins.Proteins are made up of amino acids
Which are the proteins that form the muscle?
Muscles are built from amino acids that occur in our diets. The most abundant amino acid in muscle tissue is called glutamine.
What are the building blocks of protein?
Amino acids.
What is the ratio of an amino acid?
Amino acid refers to one of a class or organic compounds that contain NH2 and the COOH group. They amino acids usually occur naturally in plants and animal tissues.
Does protein synthesis require energy to occur?
Yes, protein synthesis requires energy to occur. This energy is needed for the process of assembling amino acids into proteins.
What is the function of amino acid?
They make up proteins.
