Glycine (Gly) is most likely to be found outside of the highlighted or shaded regions on a Ramachandran plot because it has the smallest side chain (a hydrogen atom), which provides it with the greatest flexibility among all amino acids. This allows glycine to adopt conformations that are not easily accessible to other amino acids.
