Question

Quizplus · Accepted Answer

The side (R) group is the only part of the amino acid that varies, making it unique from other amino acids. The carboxyl group, alpha carbon, and amino group are present in all amino acids and are part of their defining structures. Hydrogen bonding is not a structural feature of amino acids, but a type of chemical interaction that occurs between molecules.
