Click on the 'related links' below it will take you to a wikipedia article on acids there is a list of acids there.
amino acids?? 20 amino acids
Oligopeptides are composed of 2 to 20 amino acids. They are shorter than polypeptides, which typically consist of more than 20 amino acids.
Radium don't contain acids !
20
The name given to the monomers of proteins is amino acids.
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.
Amino acids

Amino acids are the building blocks of proteins. Proteins are simply chains of amino acids. I think you meant to ask do proteins have amino acids. Amino acids as the name indicates (Amino) have amine groups, carboxylic acid groups and a side chain that varies depending on the amino acid (20 differnet types).
Enzymes are proteins composed of 20 different amino acids, so the number of possible combinations of amino acids in an enzyme is vast, with 20 amino acids at each position in the protein chain. The total number of potential combinations is calculated as 20 raised to the power of the number of amino acids in the enzyme.
There are 400 possible dipeptides formed from the combination of 20 common amino acids (20 x 20 = 400). This is because each dipeptide consists of two amino acids and each amino acid can be paired with any of the other 20 amino acids.
There are twenty amino acids, of which around half are made in the body. The other 10 are called 'essential amino acids', because they cannot be formed in our cells, so we must take them in, in our diet.
