No one knows, however there are several scientific theories. Personally, I believe it was by chance because neither L or D amino acids are thermodynamically, sterically, chemically or physically favored.

Are charged amino acids polar in nature?

Yes, charged amino acids are polar in nature.


What are protein that do not contain amino acids?

Proteins by nature are made of amino acids...so none of them.


What is the monomer for protein?

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.


Is amino acids soluble in water?

Yes, amino acids are generally soluble in water due to their polar nature. This solubility allows them to interact with water molecules through hydrogen bonding, making them readily dissolve in aqueous environments.


What are the monomers for the polymers in proteins?

The monomers of proteins are called Amino Acids.


What is the relationship between protein and amino?

Protiens are nothing but simply polypeptide chain of amino acids. In other terms amino acids are the building blocks of protiens. The specific sequence of amino acids determine the nature of protien they produce. -Anant


Is amino acid nonmetallic?

Amino acids are organic compounds containing both amino and carboxyl functional groups. These functional groups are nonmetallic in nature, making amino acids themselves nonmetallic substances.

No. Almost all vegetarian foods have a variety of amino acids.


What is the difference between amino acids and L amino acids?

D & L amino acids are both optical isomers of each other; i.e. they're compounds with the same molecular formula but different spatial arrangements. Every optically active compound has a D- and an L- isomer. They ONLY differ in their ability to rotate plane polarized light in opposite directions.


Proteins are formed of building blocks called?

Amino acids held together by peptide bonds.


Is amino acid insoluble?

Amino acids are generally soluble in water due to their hydrophilic nature. However, the solubility of a specific amino acid can vary depending on its side chain properties. Some amino acids may have limited solubility in nonpolar solvents but are usually soluble in water.


What is the monomer for building a protein?

Amino acids. There are twenty different amino acids that nature uses routinely to produce proteins. Nature has a very specific order for incorporating these amino acids to produce any specific protein. This order is coded by the genes of the organism and in an elaborate way, the code is interpreted into the order of amino acid incorporation during protein synthesis.
