Conformational isomers, or rotamers, are molecules with the same formula but different spatial atom orientations due to single bond rotations. Examples like ethane, butane, and cyclohexane illustrate their role in molecular stability and energy profiles. This concept is vital in understanding protein folding, enzyme function, organic synthesis, drug design, and polymer properties. Conformational isomerism's significance lies in its influence on chemical reactivity and biological processes.
