Based on the 20 amino acids found in proteins, there are 6840 possible variations in a polymer composed of just three amino acids.

<h3>What are amino acids?</h3>

Amino acids are the molecules from which protein molecules are made from.

There are 20 common amino acids from which protein molecules are built up from.

The amino acids are joined one to another in the protein by peptide bonds.

In a polymer composed of three amino acids, the possible variations are calculated by permutation.

The possible variations are 20 permutation 3.

nPr = n!/(n - r)!

where n = 20 r = 3

nPr = 20!/(20 - 3)!

  nPr = 6840

Therefore, there are 6840 possible variations in a polymer composed of just three amino acids.
