Biomolekularno prepoznavanje - o mogućim kvantnim prilazima

Abstract

Two unresolved issues of the (semi)classically addressed problems in molecular biophysics are unreasonably long time necessary for the change of biopolymer conformations and long-range directedness of selective biomolecular recognition processes - implying their essential quantum origin. In this paper several possible quantum approaches to biomolecular recognition are considered: Theory of Non-Radiative Resonant Structural Transitions, Model of Quantum Decoherence, and Resonant Recognition Model. These approaches might be of fundamental importance in understanding underlying macroscopic quantum-holographic Hopfield-like control mechanisms of morphogenesis, and their backward influence on the expression of genes, with significant potential psychosomatic implications.

Quantum Decoherence and Quantum-Holographic Information Processes: From Biomolecules to Biosystems

Dejan I. Raković, M. Dugić, M.B. Plavšić +3 more

Our recently proposed quantum approach to biomolecular recognition processes is hereby additionally supported by biomolecular Resonant Recognition Model and by quantum-chemical theory of biomolecular non-radiative resonant transitions. Previously developed general quantumdecoherence framework for biopolymer conformational changes in very selective ligandproteins/ target-receptors key/lock biomolecular recognition processes (with electron-conformational coupling, giving rise to dynamical modification of many-electron energy-state hypersurface of the cellular quantum-ensemble ligand-proteins/target-receptors biomolecular macroscopic quantum system, with revealed possibility to consider cellular biomolecular recognition as a Hopfield-like quantum-holographic associative neural network) is further extended from nonlocal macroscopicquantum level of biological cell to nonlocal macroscopic-quantum level of biological organism, based on long-range coherent microwave excitations (as supported by macroscopic quantum-like microwave resonance therapy of the acupuncture system) - which might be of fundamental importance in understanding of underlying macroscopic quantum (quantum-holographic Hopfieldlike) control mechanisms of embryogenesis/ontogenesis and morphogenesis, and their backward influence on the expression of genes.

A possible decoherence-based quantum-holographic Hopfield-like approach to biomolecular recognition is considered. This might be of fundamental importance in understanding underlying macroscopic quantum-holographic Hopfield-like control mechanisms of morphogenesis, with significant potential holistic psychosomatic implications.

Biopolymer Chain Folding and Biomolecular Recognition: A Quantum Decoherence Theory Approach

Dejan I. Raković, M. Dugić, M.B. Plavšić

In this paper we describe the biopolymer chain folding problem in the framework of the so-called quantum decoherence theory. As we propose a rather qualitative scenario yet bearing generality, it seems this provides promising basis for the solution-in-principle of the (semi) classically hard kinetic problem of biopolymer chain folding from coiled to native conformation in highly selective ligand proteins/target-receptors biomolecular recognition processes, implying underlying macroscopic quantum nonlocality on the level of biological cell.

On Macroscopic Quantum Phenomena in Biomolecules and Cells: From Levinthal to Hopfield

Dejan I. Raković, M. Dugić, J. Jeknić-Dugić +3 more

In the context of the macroscopic quantum phenomena of the second kind, we hereby seek for a solution-in-principle of the long standing problem of the polymer folding, which was considered by Levinthal as (semi)classically intractable. To illuminate it, we applied quantum-chemical and quantum decoherence approaches to conformational transitions. Our analyses imply the existence of novel macroscopic quantum biomolecular phenomena, with biomolecular chain folding in an open environment considered as a subtle interplay between energy and conformation eigenstates of this biomolecule, governed by quantum-chemical and quantum decoherence laws. On the other hand, within an open biological cell, a system of all identical (noninteracting and dynamically noncoupled) biomolecular proteins might be considered as corresponding spatial quantum ensemble of these identical biomolecular processors, providing spatially distributed quantum solution to a single corresponding biomolecular chain folding, whose density of conformational states might be represented as Hopfield-like quantum-holographic associative neural network too (providing an equivalent global quantum-informational alternative to standard molecular-biology local biochemical approach in biomolecules and cells and higher hierarchical levels of organism, as well).

Quantum-Informational Macrophenomena in Biomedicine & Holistic Psychosomatics: Quantum-Holographic Framework

Dejan I. Raković

The Hopfield-like quantum-holographic framework for macroscopic quantum phenomena in biomolecular folding, integrative medicine, transpersonal psychology, and holistic psychosomatics is outlined.This might have significant implications for better understanding of quantumholographic feedback control mechanisms of morphogenesis, and healing boundary conditions in acupuncture-based and consciousness-based holistic psychosomatics.

Macroscopic Quantum Effects in Biophysics and Consciousness

Dejan I. Raković, M. Dugić, Milan M. Ćirković

Abstract. It is shown that investigations in the field of microwave resonance stimulation of the acupuncture system, as well as investigations of the interactions of consciousness with microscopic and macroscopic environment- imply the existence of local and nonlocal macroscopic quantum biophysical effects, with great potential implications in medicine, psychology, biology, physics, engineering, and philosophy/religion. The parallels between classical and quantum Hopfield-like neural networks were also emphasized, as well as biophysical quantum-relativistic model of altered and transitional states of consciousness, the roots of relative metatheory of consciousness in the quantum decoherence theory, and anthropic "coincidences " in classical and quantum cosmology.
