Stochastic approach in biochemical research

The logic foundations of the probabilistic style for thinking and its methodological significance in the modern science are given. Complex, joint, ambiguous systems are the object of biochemical investigations at all organization levels and therefore biochemists often cannot obtain unambiguous results. It is shown that such systems are subjects to the study with the use of propositions of the probability theory which considers "random" events as a result of many-channel determination and is aimed to transform knowledge of these events into events predicted with certain probability. This provides a more profound analysis of a sum of facts and specificity of their theoretical interpretation. It is proved expedient to apply the probabilistic approach to study intramolecular and intermolecular interaction of elements, to characterize enzymes and membranes, to investigate objects comparatively and chemotaxanomically. It is stated that comprehension of "random" as a manifestation of a part of a sum of the possible or one of its variants stimulates the theoretical generalization of facts, elucidation of regularities of functioning, adaptation, development and diversity of every living thing.
