Practice question

Rotation around N-Cα bond is the scientifically accurate answer to this question. Within the study of Peptide and Ramachandran plo, this concept is well-established through extensive research and is documented in standard scientific literature. The specific properties, mechanisms, or characteristics of Rotation around N-Cα bond directly address what is being asked. Among the other options, Rotation around Cα-C bond, Rotation around C-N bond, and Rotation around C=O bond do not correctly answer this question because they either refer to different concepts, describe properties of other molecules or processes, or represent common misconceptions about this topic.
