Amino acids can be distinguished from one another by
A) the number of R groups found on the amino acid molecules.
B) the chemical properties of their R groups.
C) the type of bond between the R group and the rest of the amino acid molecule.
D) the chemical properties of their amino and carboxyl groups.

Question

Quizplus · Accepted Answer

Amino acids have the same basic structure consisting of an amino group, a carboxyl group, and a side chain (R group). The distinguishing feature of amino acids is their side chains, which can vary significantly in their chemical properties. The chemical properties of the R groups determine the unique properties of each amino acid, such as their solubility, acidity, reactivity, and ability to interact with other molecules. Therefore, the best way to distinguish between different amino acids is by the chemical properties of their R groups. The other options may also be relevant to some extent, but they are not as useful as the R group properties for distinguishing between amino acids.
