Information characteristics of organic molecules

The method of estimating the amount of information in the molecules, including those whose description is stored in An Information Portal to Biological Macromolecular Structures (Protein Data Bank), is described and substantiated. The connection of different base pairs is considered and the estimates of the volume of information in the compounds of the DNA strands are provided for specific pairings and atypical compounds. It is shown that nature has formed standard connections, linking the bases into a coherent whole, the structure of which contains the maximum amount of information. The effectiveness of the information approach to explore the natural (physical, chemical, and biological) systems is confirmed.
