Area of Science:

  • Biophysics
  • Physical Chemistry
  • Polymer Science

Background:

  • Physicochemical systems involve linkage potentials related to energy per mole of a reference component.
  • Macromolecules, particularly polyfunctional ones, are central to understanding these potentials.
  • Existing models may not fully capture higher-order interactions in biopolymer binding.

Purpose of the Study:

  • To introduce and define the concept of binding capacity.
  • To extend the understanding of linkage phenomena to include both chemical and physical ligands.
  • To explore the impact of thermodynamic stability on generalized binding in biopolymers.

Main Methods:

  • Conceptual development based on physicochemical principles.
  • Application of thermodynamic stability concepts.
