New Chemical Dualities Illustrated by Meso and C2 Symmetrical (CTS) Compounds

The most important relationship between chemistry and genetics is nonetheless the corpuscular nature of their objects, molecules (or atoms) and genes, respectively. On the other hand, one states, without a substantial proof, that philosophy should be one step ahead all sciences. Here is a proof that the reverse can also be true. Two internal enantiomeric halves of meso compounds or the two chiral halves of ­C2 symmetrical isomers constitute pairs of entities suitable to work as duality phenomena in science. Four types of isomers have been identified: (A) meso, (B) C2 symmetrical (CTS), (C) irregular chiral (irrechi) and (D) constitutional (constit.). Meso and CTS are characteristic to plants and microorganisms. Almost all natural micromolecular compounds from vertebrate tissues are asymmetric, i.e. they are constit. isomers. An exception to this rule is meso-inositol, an isomer of hexoses, which are themselves, as their congeners asymmetric. By comparing the real (envisaged) meso isomers of these compounds with the asymmetric ones of vertebrate tissues, the reason for nature selected the latter became quite evident: it is the omission of a suite of structural restrictions. Delivering of meso isomers of natural compounds discloses a huge chemical philosophical potential of this issue. An intrinsic property of meso combinations is their character of dimerism, hence their molecule is formed of two entities that are contrary in a spatial, chemical and optical sense, i.e. good candidates for a duality concept. Moreover, a good deal of material is indicated, i.e. CTS isomers, whose sides are chiral and identical, for a new type of duality in philosophy, strongly expressed in nature by a chemical language.
