A Ramachandran plot is a visual representation of the main-chain conformational tendencies an amino acid. Despite forty years research, shape plots still matter debate. The issue in making based on experimental data deciding whether sparse represent genuine conformations. We present here simple solution to settle ambiguities data, and explain how we verified accuracies our using independent dataset. To obtain results, then measured pair-wise distances among acids, showed that relationships acids are well preserved two-dimensional map, leading conclusion diversity space largely two dimensional. further noticed early late evolutionary stages located different zones map. In addition these conclusions, acid substitution table derived from data.
