We consider a liposome filled with the aqueous solution of an osmotic solute enclosed in a large water bath. Due to osmotic pressure, it works according to a sequence of cycles with two stages. In the first stage, the lipid vesicle with a certain inp

A criterion for systematization of organic compounds is described. Organic compounds (estimated to 16-20 millions) are of three types: (A) symmetric (especially meso and C2 symmetric), (B) possible symmetry generators, i.e. compounds possessing a rea

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

At most four types (groups) of isomers have been revealed, in natural things or as envisaged structures: meso, C2 symmetrical, irrechi, constitutional. In vertebrate almost exclusively constitutional isomers have been found. On the other hand, all fu

It is believed that the place called Bermuda triangle is able to hide of human seeing objects entered its area. A Bermuda triangle in chemistry is able to hide (mask) atoms or planar molecular fragments cut by their mirror plane of symmetry, not of h

Methylation of a hydroxy group annihilate or at least decrease the capacity of that group to form hydrogen bonds. The effect is still more pronounced by the reduction of a hydroxy group to a methylene (deoxy) one. The major methyl donor in the cells
