The R group is what allows amino acids to form macromolecules with different properties. every amino acid has the same basic structure, the only difference is what the R group is made up of. The similarities allow the amino acids to form a chain while the differences allows them to have different functions. Hope this helped!
Some examples are alcohol fermentation, lactic acid fermentation and in decomposition of organic matter.
