Summary

This study proposes a new wave model of liquid structure, explaining cellular coherence and enzyme function through water clusters exerting pressure. This challenges traditional models dominated by thermal energy, offering insights into the sub-cellular world.

Area of Science:

  • Biochemistry
  • Biophysics
  • Physical Chemistry

Background:

  • Enzymes, essential molecular nanomachines, are often modeled inaccurately in empty space, ignoring the cellular environment.
  • Current thermodynamic explanations of water-protein interactions are limited by the dominance of disruptive thermal energies.
  • Existing models fail to explain the coordinated movement and coherence observed at the sub-cellular level.

Purpose of the Study:

  • To propose a novel wave model of liquid structure based on molecular clusters.
  • To explain the origin of macroscopic pressure at the molecular level.
  • To provide a new theoretical framework for understanding sub-cellular stability, movement, and cellular coherence.

Main Methods:

  • Conceptual development of a wave model for liquid structure.
  • Analysis of water cluster formation and its role in pressure.
  • Theoretical exploration of molecular tension versus thermal energy dominance.

Main Results:

  • Water clusters, not single molecules, are identified as the source of macroscopic pressure.
  • A 'pressure pixel' concept is introduced, defining pressure at the scale of a single water cluster.
  • Molecular tension, rather than random collisions, is proposed to explain sub-cellular stability and coordinated movement.

Conclusions:

  • The wave model of liquid structure offers a more accurate representation of the sub-cellular environment.
  • This model provides a thermodynamic explanation for water-protein interactions, overcoming limitations of previous theories.
  • The proposed mechanism explains cellular coherence and the coordinated function of molecular nanomachines.
