Symmetry Culture and Science 34(1):061-086 By proposing a numbering of the twenty proteinogenic amino acids deduced from the physicochemical properties of the four coding DNA nucleobases, it is established that this amino acid number, equal to 5x entities, is not arbitrary. Indeed, we demonstrate that many attributes of these twenty amino acids, as a whole, are also 5x in number and that by isolating, since their numbering, the 3x peripheral amino acids from the 2x internal ones, these attributes are divided into ratios of 3/2 as exact value. This is verified both as the physicochemical properties of the 20 amino acids and as the coding configurations of the nucleobases, the source of this numbering. https://www.researchgate.net/publication/370897007_Numbering_of_the_twenty_proteinogenic_amino_acids_and_new_alphanumerical_nomenclature_proposal_to_them Depending on their numbering (external or internal): synthesis of the distribution of the prime attributes (to 5x in number) related to the 20 proteinogenic amino acids in exact 3/2 ratios.
