Quizplus · Accepted Answer

The side group, also known as the R-group, is the element of the chemical structure that differentiates one amino acid from another. The side group can be a variety of different structures, including simple alkyl groups, aromatic rings, and complex functional groups. It is the variation in side groups that gives amino acids their distinctive properties and allows them to perform different functions within the body. The other answer choices are not the primary factor in distinguishing one amino acid from another.
