The splitting of AAs into polar (light ton) and non-polar (bold, dark ton). The polarity as hydropathy . The number of atoms within AAs molecules (side chains) in first two rows as well as in second two columns is identical (84 atoms). The same is valid for other three rows in relation to first two columns (120 atoms). In the red frame are the polar charged AAs. The numbers marked in red represent the number of atoms in polar uncharged and nonpolar amino acids. As we can see, the balances apply both ways: in the set of all 20 amino acid molecules, as well as in the subset of polar charged and subset of all the others. (Note: The classification of amino acids into 5 polar charged, 7 non-polar and 8 polar non-charged corresponds to a unique situation in the series of natural numbers; with a series determined by the law of genetic nature (the follower contains the predecessor) (Survey 8). [Note: Here one can notice a vice-versa change in the positions of phenylalanine and proline: from F-P in Tables and.1, to P-F in this Table . Just such a change (balancing and nuancing, according to the definitions given in: MMR, 2018a, p. 33) creates the conditions for the distinction (classification) of amino acids into 5 polar charged, 7 non-polar and 8 polar non-charged, corresponding to a unique genetic mathematical series (Survey 8).] Everything is the same as in the previous Table , with the fact that here distinctions (in the number of atoms) are given in the subset of polar-charged AAs and subset of all others. Considered so separately, through columns and rows, changes are for ± 1 and ± 3. On the other hand, the quintet changes are for ± 3. All together can be compared to the system-arrangement (ordered by similarity within molecules classes) in Table Everything is the same as in the Table given in the previous paper ) (arXiv:2108.01563v4 [q-bio.BM]) with the fact that here, along with the diagonal, a distinction has been added to the subsets of polar-charged and all other AAs: "A specific protein amino acids arrangement: The first row is repeated at the bottom, and thus one cyclic system is obtained. There are 117 atoms in two outer columns; at even positions 118, at odd 119; in two inner columns 120 atoms. On the other hand, in the lower half of the Table there are 117 atoms ones more; in the lower diagonally 'wrapped' area 118, and in the upper 119; in the upper half of Table atoms. The repeated four AAs at the bottom of the Table make to achieve a diagonal balance with a difference of only one atom; moreover, to establish a sequence from the series of natural numbers: ). )
