Amino acids have similar structures. What part of an amino acid’s molecular formula distinguishes the macromolecule from other amino acids?

Answer 1

The part of an amino acid’s molecular formula that distinguishes it from other amino acids is the side chain, also known as the R group. The side chain is a unique group of atoms that is attached to the central carbon atom of the amino acid. This side chain determines the chemical properties of the amino acid and is responsible for the differences between the various amino acids.
